When receiving a forward command, motor will rotate in
counterclockwise direction (see from output side).
When r eceiving a r ev erse command, motor wil l r otate i n
clockwise direction (see from output side).
When encoder rotates in clockwise direction (see from input side).
At this moment, A phase leads B phase.
13.01 PG Pulse Range
Settings 1 to 20000 Factory Setting: 600
A Pulse Generator (PG) is used as a sensor that provides a feedback signal of the motor
speed. This parameter defines the number of pulses for each cycle of the PG control.
This parameter setting is the resolution of encoder. With the higher resolution, the speed
control will be more precise.
13.02 Motor Pole Number (Motor 0) Unit: 1
Settings 2 to 10 Factory Setting: 4
The pole number should be even (can’t be odd).
13.03 Proportional Gain (P) Unit: 0.01
Settings 0.0 to 10.0 Factory Setting: 1.0
This parameter is used to set the gain (P) when using PG for the closed-loop speed control.
The proportional gain is mainly used to eliminate the fault. The large proportional gain(P) will
get the faster response to decrease the fault. Too large proportional gain will cause large
overshoot and oscillation and decrease the stable.
This parameter can be used to set the proportional gain (P) to decide the response speed.
With large proportional gain, it will get faster response. Too large proportional gain may cause
system oscillation. With small proportional gain, it will get slower response.
