Description: Parameter for configuring the connection and disconnection of external motors to and from the line voltage (stag-
ing/de-staging).
Connecting external motors to the line voltage enables up to three additional drives to be controlled by the technol-
ogy controller in addition to the main drive. The complete system, therefore, comprises one closed-loop-controlled
main drive and up to three other drives, which can be controlled via contactors or motor starters. The contactors or
motor starters are switched by the converter's digital outputs (see also r2379).
Staging:
If the main drive is operated at maximum speed and the deviation at the technology controller input increases fur-
ther, the control will in addition connect external motors M1 through M3 to the line voltage. At the same time, the
main drive is ramped down to the staging/de-staging speed (p2378) via the down ramp, so that the total output
power can be kept as constant as possible. During this time the technology controller is switched off.
De-staging:
If the main drive is operated at minimum speed and the deviation at the technology controller input decreases fur-
ther, the control will disconnect external motors M1 through M3 from the line voltage. At the same time, the main
drive is ramped up to the staging/de-staging speed (p2378) via the up ramp, so that the total output power can be
kept as constant as possible.

Note: Selecting 2X means that a motor is switched in with twice the power (as opposed to 1X, which equates to the motor
power at the converter).
