5.2.20 Slack Cable Detection
IMPULSE
®
•VG+ Series 4 offers Slack Cable Detection for hoist applications. The Slack Cable condition is
detected when the torque output is drastically reduced and has dipped below a set-point (C11-03) level. When
Slack Cable condition occurs, the output action is defined by the C11-02 which has six selections.
The Slack Cable Detection is not executed, unless both of the following conditions are true:
• The output frequency is between C11-04 and C11-06.
• The Slack Cable Detection delay time is between C11-05 and C11-07.
Setup Procedure:
• Set the Slack Cable Detection torque level (C11-03), by lowering the hoist without load at a constant speed that
the hoist would normally run during the operation. Monitor and record the torque reference (U01-09). Repeat
the above operation several times to ensure an accurate reading.
• Then set C11-03 = [(U01-09)-2].
• Enable Slack Cable Detection by setting the C11-01 to 1.
• Select output action when Slack Cable is detected by defining C11-02.
