Parameter Function
P2366[0...2] Delay before stopping
motor [s]
With hibernation enabled. If the frequency demand drops below the threshold there is a delay of P2366 sec-
onds before the inverter is stopped.
P2367[0...2] Delay before starting
motor [s]
With hibernation enabled. If pulses have been disabled by the unit going into hibernation, and the frequency
demand has increased to above the hibernation threshold, there will be a delay of P2367 seconds before the
inverter restarts.
P2370[0...2] Motor staging stop mode 0 - 1
Selects stop mode for external motors when motor staging is in use.

P2371[0...2] Motor staging configura-
tion
Selects configuration of external motors (M1, M2) used for motor staging feature.

Caution: For this kind of motor application it is mandatory to disable negative frequency setpoint!
Note: Motor staging allows the control of up to 2 additional staged pumps or fans, based on a PID control system.
The complete system consists of one pump controlled by the inverter with up to 2 further pumps / fans con-
trolled from contactors or motor starters.
The contactors or motor starter are controlled by outputs from the inverter.
The diagram below shows a typical pumping system.
A similar system could be set up using fans and air ducts, instead of pumps and pipes.
