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
NB!
This parameter cannot be adjusted while the motor is running.
NB!
Digital input should be set to [0]

Parameter group for configuring the DC brake and DC hold functions.
2-00 DC Hold/Preheat Current
Range: Function:
50 %* [Application dependant] 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
.
NB!
The maximum value depends on the rated motor current.
Avoid 100 % current for too long. It may damage the motor.
2-01 DC Brake Current
Range: Function:
50 %* [Application dependant] Enter a value for current as a percentage of the rated motor current I
M,N
, see par. 1-24
Motor
Current
. 100% DC braking current corresponds to I
M,N
.
DC brake current is applied on a stop command, when the speed is lower than the limit set in
par. 2-03
DC Brake Cut In Speed [RPM]
; when the DC Brake Inverse function is active; or via the
serial communication port. The braking current is active during the time period set in par. 2-02
