2.2 List of parameters
Description: Sets the times for firing pulse chopping on the armature current converter.
Index: [0] = Length of first pulse
[1] = Length additional pulses
[2] = Break length
Note: The parameter is only effective on the Control Module.
Block pulses are generated (i.e. firing pulses without pulse chopping) with the following setting:
- p51826[0] = 105 µs
- p51826[1] = 105 µs
- p51826[1] = 0 µs
Description: Sets the threshold for temperature monitoring on the Control Module.
Index: [0] = Temperature sensor 1 / XT5 / A7109
[1] = Temperature sensor 2 / XT6 / A7109
[2] = Temperature sensor 3 / XT7 / A7116
Dependency: Refer to: p51830
Refer to: F60067
Note: The parameter is only effective on the Control Module.
Description: Sets the sensor type for the temperature sensors on the Control Module.
Value: 0: No temperature sensor present
1: NTC with 6.8 kOhm
2: NTC with 10 kOhm
Index: [0] = Temperature sensor 1 / XT5 / A7109
[1] = Temperature sensor 2 / XT6 / A7109
[2] = Temperature sensor 3 / XT7 / A7116
Dependency: Refer to: p51829
Refer to: F60067
Note: The NTC temperature sensor should be connected at module A7109 or A7116 at terminal XT5, XT6 or XT7.
The parameter is only effective on the Control Module.
