6 Starting and Operating
U­651 Rotation Stage MP136E Version: 1.3.0 27
Starting the U­651

Start the axis (refer to the controller manual).
Starting involves the following steps:
−
Selecting the positioner type
−
Defining the reference point of the axis
−
Commanding initial motion in closed-loop operation for testing and for running the
mechanics in
The controller manual describes startup using the PIMikroMove program.
6.3 Adjusting Parameter Values when Using Extension Cables
INFORMATION
It may be necessary to optimize the motor performance when using extension cables. The
parameter values in the controller must be adjusted if the total cable length exceeds 3 m
(between positioner and controller).

If the total cable length between the positioner and the controller exceeds 6.5 m, contact
our customer service department (p. 33).
Adjusting parameter values when using extension cables
1. Adjust the value of the Frequency Shift parameter (ID 0x64) in the controller. Possible
values: 20, 15, 10, 5, 0, -5, -10, -15, -20.
2. Repeat step 1 until the U-651 has reached optimal motor power.
3. Save the new parameter values to a positioner database on the PC or the nonvolatile
memory of the controller for future use (refer to the controller manual and the
PIMikroMove manual).
