DANGER
Electrical Shock Hazard
Do not connect or disconnect wiring while the power is on.
Failure to comply will result in death or serious injury.
Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply
is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric shock,
wait at least one minute after all indicators are OFF and measure the DC bus voltage level to confirm safe level.
WARNING
Do not operate equipment with covers removed.
Failure to comply could result in death or serious injury.
Do not perform work on the drive while wearing loose clothing, jewelry or without eye protection.
Failure to comply could result in death or serious injury.
Remove all metal objects such as watches and rings, secure loose clothing and wear eye protection before beginning work
on the drive.
Do not remove covers or touch circuit boards while the power is on.
Failure to comply could result in death or serious injury.
Do not allow unqualified personnel to use equipment.
Failure to comply could result in death or serious injury.
Maintenance, inspection and replacement of parts must be performed only by authorized personnel familiar with installation,
adjustment and maintenance of AC drives.
Before wiring terminals, disconnect all power to the equipment.
The internal capacitor remains charged even after the power supply is turned off. The charge indicator LED will extinguish
when the DC bus voltage is below 50 Vdc. To prevent electric shock, wait at least one minute after all indicators are OFF
and measure the DC bus voltage level to confirm safe level.
Fire Hazard
Tighten all terminal screws to the specified tightening torque.
Loose electrical connections could result in death or serious injury by fire due to overheating of electrical connections.
CAUTION
Crush Hazard
Do not carry the drive by the front cover.
Failure to comply may result in minor or moderate injury from the main body of the drive falling.
NOTICE
Observe proper electrostatic discharge procedures (ESD) when handling the drive and circuit boards.
Failure to comply may result in ESD damage to the drive circuitry.
Check all the wiring to ensure that all connections are correct after installing the drive and connecting any other
devices.
Failure to comply could result in damage to the drive.

C.2 MEMOBUS/Modbus Configuration
C.2
MEMOBUS/Modbus Configuration
Drives can be controlled from a PLC or other master device via serial communications using the MEMOBUS/Modbus protocol.
MEMOBUS/Modbus communication can be configured using one master (PLC) and a maximum of 255 slaves. The drive has
slave functionality only, meaning that serial communication is normally initiated from the master and responded to by the
slaves.
The master performs serial communications with only one slave at a time. The address or node for each slave must be set
beforehand so that the master can communicate with the slave at that address. A slave that receives a command from the master
will perform the specified function and then send a response back to the master.

C.6 Drive Operations by MEMOBUS/Modbus
C.6
Drive Operations by MEMOBUS/Modbus
The drive operations that can be performed by MEMOBUS/Modbus communication depend on drive parameter settings. This
section explains the functions that can be used and related parameter settings.
u Observing the Drive Operation
A PLC can perform the following actions with MEMOBUS/Modbus communications at any time regardless of parameter
settings (except H5-oo).
• Observe drive status and drive control terminal status from a PLC.
• Read and write parameters.
• Set and reset faults.
• Set multi-function inputs. Inputs settings from the input terminals So and from MEMOBUS/Modbus communications are
both linked by an OR operation.
u Controlling the Drive
To start and stop the drive or set the frequency reference using MEMOBUS/Modbus communications, an external reference
must be selected and the parameters listed below must be adjusted accordingly.

C.7 Communications Timing
C.7
Communications Timing
To prevent overrun in the slave drive, the master should wait a certain time between sending messages to the same drive. In
the same way, the slave drive must wait before sending response messages to prevent an overrun in the master. This section
explains the message timing.
u Command Messages from Master to Drive
In order to prevent overrun and data loss, the master must wait between receiving a response and sending the same type of
command as before to the same slave drive. The minimum wait time depends on the command as shown in the table below.
Table C.2 Minimum Wait Time for Sending Messages
Command Type
Example
Minimum Wait Time
• Control command (Run, Stop)
1
• Set inputs/outputs
5 ms
• Read monitors and parameter values
H5-11 = 0: 50 ms

• Write parameters
H5-11 = 1: 200 ms <1>
200 ms to 2 s, depending on the number
3
• Save changes using an Enter command
of changed parameters <1>
<1> If the drive receives command type 1 data during the minimum wait time, it will perform the command and then respond. However, if it receives
a command type 2 or 3 during that time, either a communication error will result or the command will be ignored.

A timer should be set in the master to check how long it takes for the slave drive(s) to respond to the master. If no response
is received within a certain amount of time, the master should try resending the message.
u Response Messages from Drive to Master
If the drive receives a command from the master, it will process the data received and wait for the time set in H5-06 until it
responds. Increase H5-06 if the drive response causes overrun in the master.

Message Format
u Message Content
In MEMOBUS/Modbus communications, the master sends commands to the slave, and the slave responds. The message
format is configured for both sending and receiving as shown below, and the length of data packets depends on the command
(function) content.
SLAVE ADDRESS
FUNCTION CODE
DATA
ERROR CHECK
u Slave Address
The slave address in the message defines the note the message is sent to. Use addresses between 0 and 20H. If a message with
slave address 0 is sent (broadcast), the command from the master will be received by all slaves. The slaves do not provide a
response to a broadcast type message.
u Function Code
The three types of function codes are shown in the table below.

u Data
Configure consecutive data by combining the MEMOBUS/Modbus register address (test code in case of a loopback test) and
the data the register contains. The data length changes depending on the command details.
A drive MEMOBUS/Modbus register always has a data length of two bytes. Therefore data written into drive registers must
also always have a length of two bytes. Register data read out from the drive will always consist of two bytes.
u Error Check
The drive uses a CRC-16 (cyclic redundancy check, checksum method) for checking data validity. Use the procedure described
below when calculating the CRC-16 checksum for command data or when verifying response data.
n Command Data
When the drive receives data, it calculates the CRC-16 checksum from the data and compares it to the CRC-16 value received
within the message. Both must match before a command is processed.
An initial value of FFFFH (i.e., all 16 bits equal 1) must be used for CRC-16 calculations for the MEMOBUS/Modbus protocol.
Calculate the CRC-16 checksum using the following steps:
• The starting value is FFFFH.
• Perform an XOR operation of this value and the slave address.
• Right shift the result.
• When the overflow bit of the shift operation becomes 1, perform an XOR operation of the result from step 3 above and the
fix value A001H.
• Repeat steps 3 and 4 until eight shift operations have been performed.
• After eight shift operations, perform an XOR operation with the result and the next data in the message (function code,
register address, data). Continue with steps 3 to 5 until the last data has been processed.
C
• The result of the last shift or XOR operation is the checksum.
397
C.8 Message Format
The example in Table C.3 shows the CRC-16 calculation of the slave address 02H and the function code 03H, yielding the
result D140H.
Note:
This example does not show the calculation for a complete MEMOBUS/Modbus command. Normally data would follow in the calculation.

C.9 Message Examples
u Writing to Multiple Registers
Function code 10h allows the user to write multiple drive MEMOBUS/Modbus registers with one message. This process works
similar to reading registers, i.e., the address of the first register that is to be written and the data quantity must be set in the
command message. The data to be written must be consecutive so that the register addresses are in order, starting from the
specified address in the command message. The data order must be high byte, then lower byte.
The following table shows an example of a message where a forward operation has been set with a frequency reference of
60.00 Hz for the slave 1 drive.
If parameter values are changed using the Write command, depending on the setting of H5-11, an Enter command will be
necessary to activate the data or save them. Refer to H5-11: Communications Enter Function Selection on page 394 and
Refer to Enter Command on page 415 for detailed descriptions.
