With the CV500-MC221/421 or C200H-MC221, the value displayed is 4 times
the actual value.
Proximity sensor
Z phase signal of
the Encoder
Distance
Note This function is normally used during adjustments of the system after the origin
search operations are completed.
Procedure
Use the following procedure to display the Z-phase tolerance so that it can be
monitored.
Select “5. Z-PHASE TOLERANCE” from the MONITOR mode menu.
CS1W-MC221/421, CV500-MC221/421
C200H-MC221
MON|X 1000P
ZMG|Y* 0P
|Z 11P
|U 2000P
An asterisk (
*
) indicates that the origin has not been defined.
MON|X 1000P
ZMG|Y* 0P

In this example, the tolerance for the Y axis is not displayed because the origin
search operation for the Y axis has not been completed.
The Z-phase tolerance may vary somewhat according to the speed at the time
the Z-phase is detected. This variation can be determined by means of the fol-
lowing equation:
Variation [pulses] = (Speed when Z-phase detected [p/s]) / 250
With the CV500-MC221/421 and C200H-MC221, the tolerance is always 0 for
axes using an absolute encoder.

Monitoring and Changing Servo Parameters
Caution
Confirm that no adverse effect will occur in the system before changing any set
value in memory.
Caution
Confirm that the set parameters operate correctly.
The procedure shown below can be used to monitor and change servo parame-
ters.
Note Servo parameters can only be changed for the CS1W-MC221/421 and C200H-
MC221.
Procedure 1
Use the following procedure to display servo parameters.
1, 2, 3...
1. Select “6. SERVO PARAMETERS” from the MONITOR mode menu.
Just after the power is turned ON, the X-axis residual pulse warning value is
displayed.
