11. Set the RUN/BRAKE switch to RUN, or remove the jumper
between the RB and COM terminals of terminal board
TB502.
12. Apply line voltage to the drive. The green POWER LED
shall light.
13. Set the ENABLE/DISABLE switch to ENABLE, or insert a
jumper between the ENBL and COM terminals of terminal
board TB502. The red RUN LED shall light when the drive
is enabled.
Calibrate the drive trimpots as follows.
BALANCE (BAL)
The balance setting corrects for a small offset voltage which
could be applied to the motor while the drive is in BRAKE mode.
This voltage may cause the motor shaft to continue to rotate even
after the drive and motor have been braked.
To calibrate BAL:
1. Set the BAL trimpot to the middle of its travel.
2. Set the speed adjust potentiometer or analog voltage signal to
minimum speed.
3. Apply input power.
4. Set the speed adjust potentiometer or analog voltage signal for
maximum forward speed. The motor should run at maximum
speed.
5. Set the RUN/BRAKE switch to BRAKE. If no switch is
installed, short the COM and RB terminals of connector
TB502. The motor should brake to a stop.
