Anti-Shock
Enables or disables the Anti-Shock function.
0–2
0
0 Disabled
Anti-Shock is disabled.
1 Enabled
Anti-Shock is enabled always.
2 Enbl, Not In MSpd
Disables Anti-Shock if Micro-Speed is
enabled.
C07-13
Enabling Freq
Anti-Shock is disabled until the output
frequency is above this setting.
0.0–60.0 Hz
6.0
C07-14
Re-Accel Delay
If the operator decelerates the hoist then re-
accelerates, Anti-Shock Detection is disabled
for this period of time.
0.00–2.55 sec
0.20
C07-15
Torque Delta
Torque increase required to initiate the Anti-
Shock sequence.
0–180%
10
C07-16
Detection Time
Time window to detect torque delta (C07-15).
0.01–0.50 sec
0.30
C07-17
Smoothing Freq
When the torque increase is detected, the
motor will decelerate to this frequency.
0.0–15.0 Hz
3.0
C07-18
Smoothing Decel
Deceleration time once an Anti-Shock event
has been detected. Increase this value in 0.1
sec increments if DEV faults are occurring.

display on the keypad screen for the selected
duration of time.

No Load Torque
Any torque values below this level are
ignored. Best described as the torque level
while hoisting with an empty hook (no load).
0–100%
20
C07-24
Activation Torque
In order for Anti-Shock to be triggered, the
torque increase is required to peak above this
percentage.

C07-25
Detection Method
Anti-Shock detection method.
0–2
1
0 Always Detect
Anti-Shock can be continuously detected.
1 Once Per Lift
After Anti-Shock is detected once during a lift,
it is disabled until the hoist is lowered.
2 Fault on Detect
Fault when Anti-Shock is detected.
