Parameter
Range Function
description
When the motor runs CW, the B-phase pulse advances the A-phase pulse
(when the motor runs CCW, the B-phase pulse delays from the A-phase
pulse).
Pulse command scaling function (electronic gear)
• Purpose
1) You can set-up any motor speed or work travel amount per input com-
mand pulse(unit).
2) You can increase the nominal command pulse frequency with scaling,
when your required speed can't be obtained due to the capacity of the
pulse generator of the controller(maximum available frequency).
• Block diagram of the scaling function
• The calculated numerator is max. 2621440. Set-up of larger value than
this is disabled, and automatically substituted by 2621440.

Parameters for Pulse Command Scaler (Pr46 through Pr4B)
You can invert the the phase relation between A and B phases by inverting the logic of
the B-phase pulse with this parameter.
