STEP 3
Sets a percentage value that is added to the process
reference. Applies only when at least three auxiliary
(constant speed) motors are running.

8109 START FREQ
1
Sets the frequency limit used to start the first auxiliary motor.
The first auxiliary motor starts if:
• no auxiliary motors are running
• drive output frequency exceeds limit
+ 1 Hz
• output frequency stays above a relaxed limit (
- 1 Hz)
for at least time
After the first auxiliary motor starts, output frequency
decreases by value (
In effect, the output of the speed regulated motor drops to
compensate for the input from the auxiliary motor.
E: 50.0 Hz
U: 60.0 Hz

Sets the frequency limit used to start the second auxiliary
motor. See
for a complete description
of the operation.
The second auxiliary motor starts if:
• one auxiliary motor is running
• drive output frequency exceeds limit
