Description:
Runtime error if the measured chopper current UDC_CHOP_CURR exceeds the limit 1.2 * UDC_ACT / R_BLEEDER.
External bleeder (BLEEDER_SELECTOR_EXT == 1): R_BLEEDER = R_BLEEDER_EXT
Internal bleeder (BLEEDER_SELECTOR_EXT == 0): module-depending (see user's manual e.g.: 8B0P0110xxxx.xxx-x: R_BLEEDER = 270 Ohm)
Reaction:
None.
Cause/Remedy:
Braking resistor error configuration: The parameter for the resistance value of the braking resistor R_BLEEDER_EXT was set too high.
Braking resistor defective: The real resistance value of the braking resistor has decreased.
Braking resistor defective or connections RB+ and RB-: Short-circuit
Braking resistor defective or connection RB-: Ground fault RB-
DC bus voltage measurement defective: The real DC bus voltage value is higher than the measured DC bus voltage value UDC_ACT.
Chopper current measurement defective: The measured chopper current value UDC_CHOP_CURR is too high.
The overcurrent check can be disabled by setting Bit8 (0x100) in the parameter MOTOR_TEST_MODE.
Caution: Ignoring the braking resistor overcurrent can result in damage to the ACOPOS module or the braking resistor.
