Action Motor/converter response
① Selection of SSM
• The converter detects when SSM is selected.
• If the speed of the motor is between the speed limit and the
negative speed limit, the converter sets the signal "Speed below
limit value" (p9722.15=1).
② Exceeding the velocity limit
• If the speed of the motor exceeds the speed limit, the converter
resets the signal "Speed below limit value" (p9722.15=0).
③ Falling below the velocity lim‐
it
• If the speed of the motor falls below the speed limit minues the
hysteresis, the converter sets the signal "Speed below limit val‐
ue" (p9722.15=1).
④ Falling below the negative ve‐
locity limit
• If the speed of the motor falls below the negative speed limit,
the converter resets the signal "Speed below limit value"
(p9722.15=0).
⑤ Exceeding the negative veloc‐
ity limit
• If the speed of the motor exceeds the negative speed limit plus
the hysteresis, the converter sets the signal "Speed below limit
value" (p9722.15=1).
