Overcurrent error
An overcurrent error is registered if one of the following conditions is met:
•
≥3.5 A flow from a PWM output for at least 2 seconds
•
≥5 A flow for 3 consecutive PWM cycles
In both cases, the affected PWM output is deactivated by the firmware (i.e. the pins on the PWM output are short-
circuited). The user must acknowledge the error (see 4.25.2.14.4.5 "Error acknowledgment and dither switch-off")
before a PWM output disabled in this manner can be made operational again.
Open load error
An open load error is only registered in current control mode (see 4.25.2.14.3.5 "configuration register") if the
current setpoint is not reached. In some cases this can be caused by an open line, although usually the impedance
of the load is too high.
