Status
4. Test the set limit value
4.1. Enter a negative 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
● The inverter signals the following:
– C01716 and C30716
(tolerance for safe direction of
motion exceeded)
– C01700 and C30700 (STOP A
initiated)
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)
– C01701 and C30701 (STOP B
initiated)
– C01700 and C30700 (STOP A
initiated)
4.3. Analyze the trace:
● When SDI+ is selected, the inverter signals: SDI+ is active (r9722.12 = 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 (r9722.12 = 0).
5.3. Acknowledge the messages for the safety functions.
You have completed the acceptance test of the SDI function for the positive direction of rotation.
