Note: 1. For the X- and Y-axes, adjust using the UHi parameter values first. After adjustment,
enter the mid parameter values to ensure that the travel time and overshoot are as
specified in Table 1 “Max, Travel Time and Overshoot”.
2. For the FQ, FRQ and NC-axes, adjust by using the ROT parameter values. After
adjustment, enter the REV parameter values to ensure that the travel time and overshoot
are as specified in Table 1.
3. For digital input servo amplifiers, use a loop gain value specified in the table above. No
servo adjustment is required.
If an axis does not satisfy the specs in table 1, check it again after idling the relevant axis.

5.2.2 CP-643E Servo Adjustments
When performing servo adjustments on the CP642, the machine should be booted up in
“Mechacheck mode”, the boot-up procedure for which is detailed in the section below.
Note: The procedure explained below is valid from ROM versions 305 or later.
Before Starting Adjustments
1) Boot-up the machine in “Mechacheck mode”.
[3] (axis change button) + RESET + POWER ON
Following this, both shutters should be raised to avoid collision with the device
tables.
2) Ensure the cam axis is at 0° and that all stopper solenoids are set to OFF.
3) Specify the axis to be adjusted:
[SERVO] → [+ PAGE], [- PAGE]
4) Prepare axis movement:
[SERVO MOVE]
5) Perform zero-setting.
Zero Adjustment
<D-Axis>
[V_TEST] → [ZERO] → START
The current servo count appears on the screen. The value will fluctuate.
Turn the ZERO volume on the amp slowly to eliminate any fluctuation.
When the counter becomes stable, press CYCLE STOP.
Refer to the figure below for the location of the ZERO volume.
<C and X-Axis>
Connect the digital operator to the servo amplifier, and perform the automatic zero
adjustment and then manual zero adjustment.
[V_TEST] → [ZERO] → START
A changing servo counter value displays on-screen.
Automatic Zero Adjustment
[DSPL SET] → [C][n][-][0][0] displays → [DATA ENTER] → [0][0][-][0][0] displays →
[▲] → [0][0][-][0][1] displays → [DSPL SET]

Manual Zero Adjustment
→ [▲] → [0][0][-][0][3] displays → press [DSPL SET] one time
→ [A][-][*][*][*] displays
→ Press the digital operator’s [▲][▼] keys to adjust until the count value stops changing.
→ After the count value stops changing, press [DSPL SET] twice (data is stored).
→ Press CYCLE STOP to stop the operation. → [DATA ENTER] → [C][n][-][0][0]
displays → [DSPL SET]
<FQ-, FRQ-, NC-, Y- and Z-Axis>
Perform the adjustments from the panel operator on the amp itself.
Manual zero adjustment
[V_TEST] → [ZERO] → START
A changing servo counter value displays on-screen.
[MODE/SET] → [F][n[0][0][0] displays → [▲] → [F][n][0][0][A] displays
→ Press [DATA/SHIFT] for 1 sec or longer → [¯.][.][5][P][d] displays → [DATA/SHIFT]
→ [ ][*][*][*] displays
→ Press the [▲] [▼] keys to adjust until the count value stops changing.
→ After count value stops changing, press [DATA/SHIFT] → [¯.][.][5][P][d] displays
→ Press [DATA/SHIFT] for 1 sec. or longer (data is stored) → display [F][n][0][0][A]
displays
→ Press CYCLE STOP to stop the operation.
