p0251[0...n] Operating hours counter power unit fan / PU fan t_oper
SERVO_S110-CAN, Can be changed: T
SERVO_S110-DP,
Data type: Unsigned32
SERVO_S110-PN
P-Group: Modulation
Not for motor type: -
Min
0 [h]
Description: Displays the power unit fan operating hours.
The number of hours operated can only be reset to 0 in this parameter (e.g. after a fan has been replaced).
Dependency: Refer to: p0252
p0252 Maximum operating time power unit fan / PU fan t_oper max
SERVO_S110-CAN, Can be changed: T
SERVO_S110-DP,
Data type: Unsigned32
SERVO_S110-PN
P-Group: Modulation
Not for motor type: -
Min
0 [h]
Description: Sets the maximum operating time of the power unit fan.
The pre-alarm (warning) is output 500 hours before this set value.
The monitoring is de-activated with p0252 = 0.
Dependency: Refer to: p0251
Note: For chassis units, the maximum operating time in the power unit parameter is set to 50000 via the factory setting.
p0255[0...1] Power unit contactor monitoring time / PU cont t_monit
SERVO_S110-CAN, Can be changed: T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: Modulation
Not for motor type: -
Min
0 [ms]
Description: Sets the monitoring time for internal monitoring of the contactor feedback contacts.
Index: [0] = Pre-charge contactor
[1] = Bypass contactor
Dependency: Refer to: F30060, F30061
Note: This parameter is only effective for chassis power units with 3 AC line connection and line contactors.
A value of 0 de-activates the associated line contactor monitoring.
p0278 DC link voltage undervoltage threshold reduction / Vdc U_under red
SERVO_S110-CAN, Can be changed: T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: Converter
Not for motor type: -
Min
-80 [V]
Description: Sets the absolute value by which the threshold to initiate the undervoltage fault (F30003) is reduced.
Dependency: Refer to: p0210, r0296
Refer to: F30003
Notice: When using a Control Supply Module (CSM) for 24 V supply from the DC link, the minimum continuous DC link volt-
age may not lie below 430 V. DC link voltages in the range 300 ... 430 V are permissible up to a duration of 1 min.
For chassis power units, this parameter has no significance.
