5.9.1

General settings

2.9.1.1 Thermistor Fault Response
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to ID506
3 = Fault, stop mode after fault always by coasting
Setting the parameter to
2.9.1.2 OverTemp Response
2= Fault
3= Fault, Open MCB
4= Fault, Open NET CB
5 = Fault, Open Main & NET CB
2.9.1.3 Overvoltage Response
2= Fault
3= Fault, Open MAIN CB
4= Fault, Open NET CB
5 = Fault, Open Main & NET CB
2.9.1.4 CoolingFlt.Delay
Protection for liquid-cooled units. An external sensor is connected to the drive (DI:
Cooling Monitor) to indicate if cooling liquid is circulating. If the drive is in STOP state
this is only a warning. In RUN state, the drive will issue a fault with a coast stop. This
parameter defines the delay after which the drive goes to FAULT state when
signal is missing.
2.9.1.5 LCL Temperature input monitor
This parameter defines a response to the input filter overtemperature fault. The fault is
monitored through a digital input.
2.9.1.6 Max Charge Time
When the drive charging options are used, this parameter defines the maximum time
limit for charging.
5
0 will deactivate the protection.
