Parameters
Adjusting the control gain at the positioning operation
• Set [AE-66] and [AE
[Hb105] maximum frequency
• Once the positioning operation is
control starts at the speed set to the [AE
start speed.
• During the positioning operation, the speed is
limited to that set to the [AE
limit. During the positioning, the
acceleration/deceleration time is 0 and th
follows the internal position control results.
