NOTE!
Danfoss recommends using 24 V DC as the thermistor supply voltage.
1-93 Thermistor Source
Option: Function:
Select the input to which the thermistor (PTC sensor) should be connected. An analog input option
[1] or [2] cannot be selected if the analog input is already in use as a reference source (selected in
par.3-15
Reference 1 Source
, par.3-16
Reference 2 Source
or par. 3-17
Reference 3 Source
).
When using MCB112, choice [0]
None
must always be selected.
[0] * None
[1] Analog input 53
[2] Analog input 54
[3] Digital input 18
[4] Digital input 19
[5] Digital input 32
[6] Digital input 33
NOTE!
This parameter cannot be adjusted while the motor is running.
NOTE!
Digital inputs should be set to “No operation” - see par. 5-1*.
2-00 DC Hold/Preheat Current
Range: Function:
50 %* [0 - 160. %] Enter a value for holding current as a percentage of the rated motor current I
M,N
set in par.
1-24
Motor Current
. 100% DC holding current corresponds to I
M,N
.
This parameter holds the motor (holding torque) or pre-heats the motor.
This parameter is active if [1] DC hold/Preheat is selected in par.1-80
Function at Stop
.
NOTE!
The maximum value depends on the rated motor current.
NOTE!
Avoid 100% current for too long, as it may damage the motor. It may damage the motor.
