Status
4. Test the set limit value
4.1. Enter a positive speed setpoint.
4.2. The following test depends on how you have set the SDI function during commis‐
sioning:
STOP A in the event of a limit value
violation
STOP B in the event of a limit value vio‐
lation
The inverter signals the following:
● C01716 and C30716 (tolerance for
safe direction of motion exceeded)
● C01700 and C30700 (STOP A
initiated)
The inverter signals the following:
● C01716 and C30716 (tolerance for
safe direction of motion exceeded)
● C01701 and C30701 (STOP B
initiated)
● C01700 and C30700 (STOP A
initiated)
4.3. Analyze the trace
● When SDI- is activated, the inverter signals: SDI- is active (r9722.13 = 1).
● If r9713[0] > SDI tolerance, then the inverter signals an internal event
(r9722.7 = 0).
STOP A in the event of a limit value
violation
STOP B in the event of a limit value vio‐
lation
● The motor coasts down to a
standstill (r9722.0 = 1).
● The inverter brakes the motor on the
OFF3 ramp (r9722.1 = 1).
● After braking, STO is active
(r9722.0 = 1).
5. Acknowledge fault
5.1. Deselect SDI-.
5.2. Check: SDI- is not active (r9722.13 = 0).
5.3. Acknowledge the messages for the safety functions.
You have completed the acceptance test of the SDI function for the negative direction of
rotation.
