SECTION 3 : HOIST PARAMETERS
35
3.2.12. Stop Delay
NO PARAMETER DESCRIPTION SCALE INCREMENT DEFAULT
12 Stop delay Torque hold delay at
stop 300
– 1500 ms
50 ms 600 ms
This parameter sets the time for zero speed to be held at stop, to allow sufficient time for the
mechanical brake to be fully applied.
This eliminates load sagging at stop due to the slow reaction time of the mechanical brake.
3.2.13. Lower Plugg Out
NO PARAMETER DESCRIPTION SCALE INCREMENT DEFAULT
13 Lower plugg out Lower plugg time out 2000
– 5000 ms
250 ms 3000 ms
The “Lower plugging time out” time, compares the actual motor Lowering retardation profile against the
profile set by this parameter. In the event that the actual retardation is going to take longer than the set
retardation time a “Lower plug out” trip will occur.
Note: The “Lower plug out” time sets the profile for Lower retardation from 100% to 0% speed.
3.2.14. Max Stall V
NO PARAMETER DESCRIPTION SCALE INCREMENT DEFAULT
14 Max Stall V Maximum stall volts 70% to 100% 5% 80%
This parameter sets the voltage which will remain applied to the motor in the event that the motor is
stalled. It is calculated as a percentage of the supply volts.
In the event that the motor remains in a stalled condition, this voltage will be applied for a maximum
period of 10 seconds, after this time a “Motor Stall” fault will trip the system.
