712 BRAKE MONITOR
Value:
0 (DISABLE)
[0]
✭
1 (ENABLE)
[1]
Function:
This parameter allows disabling the system brake. The
parameter is used for testing the unit. For reasons of
safety the parameter has been factory set for "ON".
713 DERATE LOWERING
Value:
0.6 - 1N/A
✭
0.8 N/A
Function:
With this parameter the output during lowering is
reduced. 1.00 equals rated power output.
714 DERATE HOISTING
Value:
0.6 - 1 N/A
✭
1 N/A
Function:
This parameter is for decreasing the output power
determined by the load estimator.
715 MECHANICAL BRAKE ON DELAY
Value:
0,1 - 20 sec.
✭
0,5 sec.
Function:
The value indicates the required time before the
mechanical brake cuts in (relay 1-3). After the delay
time the system brake takes over the load.
716 MECHANICAL BRAKE OFF DELAY
Value:
0,1 - 20 sec.
✭
0,5 sec.
Function:
The value indicates the required time before the
mechanical brake is released. After the delay time,
the system brake releases the load.
718 ENCODER MONITOR
Value:
0 (DISABLE)
[0]
✭
1 (ENABLE)
[1]
Function:
This parameter makes it possible to choose between
disable and enable in order not to monitor or to
monitor the encoder hardware.
720 DRUM INERTIA 1
Value:
0 - 1kgm
2
✭
Depends on unit
Function:
This parameter is used in the load estimator to
calculate the static load on the motor by setting
the inertia of the cable drum in gear 1.
721 GEAR RATIO 1
Value:
0 - 200
✭
Depends on unit
Function:
This parameter is used in the load estimator to
calculate the static load on the motor by setting
the ratio of the gear in gear 1.
722 GEAR INERTIA 1
Value:
0 - 1 kgm
2
✭
Depends on unit
Function:
This parameter is used in the load estimator to
calculate the static load on the motor by setting
the inertia of the gear in gear 1.
723 MEAN RADIUS
Value:
0 - 2 m
✭
Depends on unit
Function:
This parameter is used in the load estimator to calculate
the static load on the motor by setting the mean radius
of the cable drum in metres with the gear in gear 1.
