hertz relationship. The motor must rotate CCW (counter clockwise) when viewed from the opposite
drive end when rotating in the forward direction. If the motor's direction of rotation is incorrect, this
must be corrected by reversing any two motor leads either at the G7 or the motor.
The programming example demonstrates the programming required when using a bi-directional,
differential line driver encoder providing 1024 pulses per revolution.

Comments
Select either 'PG Vector Control
(speed/torque switching)'
Configure the number of motor poles to
match that of the motor used
Rated capacity of the motor is kW. To
determine kW if Hp is known, multiply Hp
by 0.745
If motor used is not listed as a possible
selection, use 'Other'. and perform autotune
as last step.
Select 'Reset Motor Defaults'. The G7 will
then apply the correct motor model.
1024 (set to match PPR of encoder)
2 (use 1 if using non directional encoder)
Change to 0.01
Set to 0.00 to allow the G7 and motor to
produce holding torque at zero speed
Select #56: Control Switch (torque,postion)
Set to source of torque command. RR used
is this example
Scale RR input as required.
Select 'SETTING'
Set to desired maximum output frequency in
forward direction while in torque control
mode
Select 'SETTING'
Set to desired maximum output frequency in
reverse direction while in torque control
mode
