Description
Cascade control - status word
.00 1 signal = start uncontrolled M1 motor
.01 1 signal = start uncontrolled M2 motor
.02 1 signal = start uncontrolled M3 motor
.03 1 signal = activate motor
.04 1 signal = activation/deactivation active
.05 1 signal = all motors active
.06 1 signal = automatic replacement not possible
.07 1 signal = alarm active
Cascade control - operating hours (factory setting: 0 h)
[00] M1 motor
[01] M2 motor
[02] M3 motor
Cascade control - maximum time for continuous mode (factory setting: 24 h)
Time limit for continuous uninterrupted operation of uncontrolled motors
Cascade control - absolute operating time limit (factory setting: 24 h)
Limit for the total operating time of the uncontrolled motors
Cascade control - deactivation sequence (factory setting: 0)
0: Normal stop
1: Sequential stop:
For OFF1, the inverter deactivates the motors in the following sequence:
M3 → M2 → M1 → controlled motor
p2387 is the time between the deactivations.
Cascade control - motor switch-on delay (factory setting: 0 s)
Cascade control - stop time activation speed (factory setting: 0 s)
Cascade control - motor deactivation delay (factory setting: 0 s)
Cascade control - stop time deactivation speed (factory setting: 0 s)
