Low Volts Stop
Range: P52 / B0 Default: Off Scaling: n/a Type: R/W
This menu item turns ‘On’ or ‘Off’ the ‘Low Voltage Stop’ function. When ‘On’, this allows soft-
stop pedestals of less than 40% to be set. Soft-stop pedestals of 40% and less can be set with the
‘Low Volts Stop’ set to ‘Off’, but they will be treated by the unit as a 40% soft-stop pedestal.
Contactor Delay
Range: 100 to 800 milliseconds Default: 160 ms Scaling: n/a Type: R/W
‘Contactor Delay’. Following a start command, this is the delay allowed for the main incoming
contactor to close. After this time, a phase loss detection routine checks the incoming supply.
Trip Sensitivity
Range: 1 to 15 Default: 1 Scaling: n/a Type: R/W
‘Trip Sensitivity’ holds an arbitrary number to adjust the sensitivity of the fault trips of P-127,
‘Hidden Trip Flags’. The larger the setting of P-72, the slower the trips of P-127.
Station No
Range: 1 – 32 Default: 1 Scaling: n/a Type: R/W
‘Station Number’ assigns the Local Network ID of this card.
Firing mode
Range: 0 to 1 Default: 0 Scaling: n/a Type: R/W

• 0 = Normal Motor (outside delta or star/wye)
• 1 = Delta (inside delta no optimizing)
P122 Stop Smooth
Range: 1 to 25 Default: 5 Scaling: n/a Type: R/W
‘Auto Soft Stop Smoothing’ is an arbitrary filter to smooth soft stop jitters caused by unstable load.
This feature is turned ON or OFF by Bit 2 of Parameter 121.
