Frequently Asked Questions
What manual should I use with this Modbus guide?
Use the MC Series Installation and Operation Manual (Document M101 or M301) that shipped with your drive.
How do I change an acceleration time using Modbus?
Find the associated Modbus register number by adding 52 to the MC parameter number. For example, write the desired time into Modbus register 40060.
What is the Modbus address for controlling speed?
Set Parameter 29 (MANUAL) to KEYPAD and then write the speed to Keypad Speed Command Register, which is Modbus register 40041.
How can I read the drive's full operational status block?
Send a read command for an entire status block by reading from Modbus register 40025 using function code 03 with a register count of 6.
