MODBUS.PSCALE

Description

This parameter determines the number of encoder counts per mechanical revolution reported over Modbus.

Modbus Resolution = 2^(MODBUS.PSCALE).

Notes:

  • This scaling affects Position, Velocity and Acceleration when reading values over Modbus. This scaling term does not affect units over any other communication.
  • Additionally, see MODBUS.PIN and MODBUS.POUT, as these are applied on top of MODBUS.PSCALE to allow for user customizable units.
