Description
4-10
Single sup
Selects the action when the motor temperature exceeds the limit or when
“Fault, Br wear” occurs
No
Both hoisting and lowering is prevented
4-10-1
OT run ?
No
Down
Hoisting is prevented, lowering is allowed
4-10-2
OT limit
“nnn” C
When NTC type sensor is applied (P4-4-1 and P4-5-1) the limit value for the hoist motor
overtemperature supervision in given here in degrees Celsius, with the resolution of one degree. When
the given limit is exceeded, the overtemperature supervision is triggered. Once activated, the
supervision remains active until the motor temperature has descended 30°C under the given limit value.
Selects the supply voltage supervision.
YES
Supply voltage supervision is active
NO
Supply voltage supervision is not applied
The supply voltage supervision checks the phase order and the presence of all phases (L1, L2 & L3)
In insulated or high impedance grounded networks, selection must be NO
4-10-3
Supply sup
YES
When the control method is stepless speed control (parameter 4-8 is “INV”), selection must be NO
