Code Description
8113 LOW FREQ 2
Sets a frequency limit (see Figure 56). When ACS 400 output frequency falls below value (8113
- 1 Hz) and two auxiliary motors are running, the Stop Delay counter is started. When the time set with
parameter 8116
FREQ 2 + 1 Hz), the second auxiliary motor is stopped.
After the auxiliary motor is stopped, ACS 400 output frequency is increased by a value (8110
- 8113
LOW FREQ
Note! Low Frequency 2 should be within limits 2007
8114 LOW FREQ 3
Sets a frequency limit (see Figure 56). When ACS 400 output frequency falls below value (8114
- 1 Hz) and three auxiliary motors are running a Stop Delay counter is started. When the time set with
parameter 8116
3 + 1 Hz), the third auxiliary motor is stopped.
After the auxiliary motor is stopped, ACS 400 output frequency is increased by value (8111
