Snap Shaft Detection
The snap shaft condition is detected when the speed of two shafts changes per setting of C11-10,
delta speed, after a delay time C11-11, action of C11-09 will be taken.
C11-03 SLC Detect Torq Percentage of Output Torque
below which the enabled
Slack Cable Detection is
activated—as long as the
Frequency output is between
C11-04 and C11-06, and the
delay time is between C11-05
and C11-07. 0–100% 30 Adv
C11-04 SLC Detect Spd 1 The Frequency Output that is
required for the enabled Slack
Cable Detection to be
activated. It corresponds to
Slack Cable Detection Delay
Time 1 (C11-05). 0–150Hz 2 Adv
C11-05 SLC Delay Time 1 The delay time before the
enabled Slack Cable
Detection can be activated. It
corresponds to Slack Cable
Detection Speed 1. Prevents
false outputs. 0.00–2.55sec. 0.50 Adv
C11-06 SLC Detect Spd 2 The Frequency Output below
which the enabled Slack
Cable Detection can be
activated. It corresponds to
Slack Cable Detection Delay
Time 2 (C11-07). 0–150Hz 60 Adv
C11-07 SLC Delay Time 2 The delay time before the
enabled Slack Cable
Detection can be activated. It
corresponds to Slack Cable
Detection Speed 2. Prevents
false outputs. 0.00–2.55sec. 0.10 Adv
