CDE360 Vector Control AC Drive Chapter 6 Parameters Description
The first auxiliary pump startup conditions:
No auxiliary pump is running.
AC drive output frequency is higher than E6.10+1Hz,and the lasting
time exceeds
E6.16
.
After the first auxiliary pump startup:
AC drive reduces output frequency by a step of (
E6.10
-
E6.11
).
The reduced speed of speed-regulated motor gives a compensation to
the increment from auxiliary pump startup.See the description of
Figure below.

The frequency to remove the first auxiliary pump(controlled via a Y/T
terminal with No.41 function “Motor 2# Control output”).
The first auxiliary pump stop conditions:
Only one auxiliary pump is running.
AC drive output frequency is lower than E6.11-1Hz,and the lasting time
exceeds
E6.17
.
After the first auxiliary pump stop:
AC drive increases output frequency by a step of (
E6.10
-
E6.11
).
The increased speed of speed-regulated motor gives a compensation to
the decrement from auxiliary pump stop.See the description of Figure
below.
