3.2 Cargo Swing Suppression (Anti Swing Control)
Cargo Swing Suppression suppresses swinging of the cargo that occurs when the traverse
shaft or traveling shaft accelerates and decelerates in an overhead crane. This function is
effective for suppressing swinging of the cargo and reducing takt time by adjusting the
acceleration and deceleration times during operation. When the function is enabled, the
acceleration and deceleration times are adjusted to times that can suppress cargo swing based
on the acceleration and deceleration times set for the C parameter. For U1-16 [SFS Output
Frequency], the adjusted frequency is output by Anti Swing Control.
◆ Applicable Control Modes
• V/f Control (A1-02 = 0)
• V/f Control w/ PG (A1-02 = 1)
• Open Loop Vector (A1-02 = 2)
• Closed Loop Vector (A1-02 = 3)
• Advanced Open Loop Vector (A1-02 = 4)

Note:
• The effect of Cargo Swing Suppression when the traverse shaft or traveling shaft stops is
dependent on the mechanical configuration of the crane. Be aware that cargo swinging
caused by the lifting and lowering operation of the crane, wind, and/or the mechanical
configuration of the crane cannot be suppressed.
• Be aware that effect of Cargo Swing Suppression will be lessened when there is a large degree
of error between the length of the center of gravity position of the wire tip from the center of
the lifting and lowering shaft drum and U9-06 [Wire Length].
