7.3 Operating the drive
12. Apply power to the drive.
Slowly increase the external demand.
13.
Is the motor turning in the required direction?
If not, reverse the system by
transposing the A+ and A- motor armature connections.
CAUTION!
When reversing the system:
To prevent damage, do not transpose the
motor armature connections until the motor has stopped rotating.
14.
Increase demand to the maximum and confirm that the motor speed is approximately
correct for both directions of rotation.
15.
Fine adjust the speed using the
MAX
preset.
16.
IR COMP
: Speed droop on heavy loads may occur where armature voltage control mode
is in use. Turn the IR comp preset clockwise to compensate for this.
1. Run the motor at full speed and monitor the armature voltage.
2. When the motor is fully loaded, increase the
IR COMP
preset (rotate clockwise) to
restore the original speed.
3. The motor should now hold the same speed with or without load.
WARNING!
EQUIPMENT DAMAGE HAZARD
Excessive rotation of IR COMP can cause instability. Do NOT allow this to occur as
it may lead to damage.
NOTE: The IR COMP system works by adding extra volts to the armature:
V
extra
= Amps x armature resistance
The drive is now fully commissioned in ARMATURE VOLTAGE control mode.
