◆
Frequency Reduction Gain
This function switches to low-speed operation when the crane load is near the target position.
The frequency is adjusted by multiplying the gain against the smallest frequency reference from among
d1-01
[Reference 1] through d1-17 [Jog Reference]
as selected by the multi-step speed reference. When the external
input terminal to which frequency reduction gain is assigned turns on, the gain set to
S2-16
or
S2-17
is applied to
the normal frequency reference followed by a corresponding switch to low-speed operation.
Note:
This function is disabled when the frequency reference is held through the use of
H1-xx = A [Accel/Decel Ramp Hold]
or
H1-xx = 10 or
11 [Up/Down Command]
.
