Scaling of the drive parameters (1) Scaling of frequency is 1: 100 To run the drive at 50 Hz, the main reference should be 0x1388 (5000). (2) Scaling of time is 1: 10 To set the drive’s acceleration time to be 30 s, the function code should be set to 0x012C (300). (3) Scaling of current is 1: 10 If the drive’s feedback current is 0x012C (300), the present current is 30 A.
