Control by input PWM:
Here is similar situation. When lost signal from driving PWM generator or signal parameters go outside from limit range, or cut si gnal
wires or shorting of these wires (together or to GND), after time "masking signal drop"
P38
is activated emergency stop procedure, as in
previous cases.
Although the standard width of the control signal in the range 1-2 ms, the controller tolerates a wider area.
Control by data transfer:
Again similar situation is also in this case. When driving data transfer lost or interrupted (data transfer period is longer than limit value
P38
), when signal (data) shorting together or to GND, activate emergency stop of the motor.
