Description
MODBUS.PIN and MODBUS.POUT (s: 766) are used to apply user specified units to the feedback
values retrieved over Modbus.
To use this parameter correctly, first the MODBUS.PSCALE (s: 767) must be known, this value deter-
mines the resolution per revolution of the motor for Modbus. Then the ratio of MODBUS.POUT (s: 766)
/MODBUS.PIN is applied to convert counts/rev into User Units/rev.
Example
Use Modbus Scaling to return feedback in Radians
MODBUS.PSCALE = 16 (65536 counts/rev or pole pitch)
MODBUS.PIN = 5215189
MODBUS.POUT = 500000
If the motor is currently resting with a Modbus raw position 36,462 Counts (MODBUS.PSCALE (s: 767) is
set to return 65,536 per rev) andthe user requests the position using PL.FB over Modbus, the position will
be returned as:
36,462 * 500000 / 5215189 = 3495 (Radians * 1000)
Which equals 3.495 Radians
