(8) Adjusting the Z phase and A phase differ ence

[1] Stop the motor, and make sure that the detection gears are not rotating. The sensor could be

damaged if adjustments are carried out while the gears are rotating.

[2] Using a clearance gauge, adjust so that the gap between the sensor direction surface and the

detection gears’ circumference is 0.15±0.01mm, and loosen the sensor fixing screw.

[3] The phase difference of the Z phase to the A phase can be adjusted by rotating the sensor as

shown on the right. At this time, rotate the sensor a little bit while using the marking lines on

the sensor and installation seat as a guide.

[4] Tighten the sensor fixing screw so that the sensor

does not move, and confirm that the gap between the

sensor detection surface and detection gears'

circumference is 0.15 ± 0.01mm. Then, rotate the

gears and confirm the phase difference as explained

above.

[5] When the phase difference is within the tolerable

range, apply a locking agent on the sensor fixing

screw, and then fix the sensor. Check the gap again

after fixing the sensor.

Always carry out the initial automatic adjustment when starting the spindle system up for the first

time or when the spindle drive unit has been replaced.

3-6-2 Z phase automatic adjustment

Z-phase automatic adjustment is a function that automatically adjusts the relative position of the IPM

spindle motor pole and the PLG Z-phase pulse signal input into the spindle drive unit. The adjustment

data is saved in the drive unit, and is used to control the motor the next time the power is turned ON.

The motor cannot be started without completing this adjustment (alarm 16 will be detected), so always

carry out this adjustment when starting up the spindle system, when the spindle motor has been

replaced, when the PLG has been replaced or adjusted, or when the spindle drive unit has been

replaced.

[1] If SP205 is set to 1, change it to 0, and reboot the NC power. If it is already set to 0, go to step

[2].

[2] If the SP205 setting is 0, change it to 1.

[3] Input forward run start. The spindle motor will automatically rotate at the adjustment speed

(two stages for Z-phase pulse detection and pole position detection). (The control output

4/bitD is changed to 1 on the NC spindle monitor screen from startup until a restart occurs. In

the same manner, the control input 3/bit8 or bit9 status of 1 is established after the forward run

start input, and "D" is displayed for the drive unit until automatic adjustment is completed.)

[4] The adjustment results will be calculated and the operation will automatically stop approx. 90

seconds after forward run is started (may vary according to pole position). (When automatic

adjustment is completed, the drive unit display at the NC spindle monitor screen changes from

"D" to "C". Even though the motor is stopped while "D" is displayed, automatic adjustment is in

progress. Be sure to wait until "C" displays.)

[5] Turn forward run OFF. (The adjustment data will be saved.)

[6] Reboot the NC power.

POINT

1. If the NC power is turned ON when SP205 is set to 1, the adjustment data

saved in the drive unit will be used for control.

2. To readjust, or to turn the start OFF during the automatic adjustment when

"D" is displayed for the drive unit (see step [4] above), specify another

SP205=0 setting to restart the NC, then perform the above procedure,

beginning from step [2].

3. If operation is started without completing the adjustment, alarm 16 will occur.

CAUTION

1. The motor will automatically rotate at the adjustment speed during Z-phase

automatic adjustment. Do not touch the rotating sections as this is

hazardous.

2. Complete PLG adjustment before starting this adjustment. (Built-in motor)

3. Keep the spindle load inertia and friction load as small as possible when

using this function. (The maximum inertia is approx. 5-fold the motor

inertia.)

3-6-3 Motor end PLG automatic adjustment

Motor end PLG automatic adjustment is a function that automatically adjusts the gain and offset of the

spindle motor built-in PLG's A and B phase sine wave signals which are input into the spindle drive unit.

The adjustment data is saved in the drive unit, and is used to control the motor the next time the power

is turned ON.

Always carry out this adjustment when starting up the spindle system, when the spindle motor has

been replaced, when the PLG has been replaced or adjusted, or when the spindle drive unit has been

replaced. This function is used to improve the accuracy of the position data.

When using the IPM motor (MDS-C1-SPM), complete the "3-6-1 Z-phase automatic adjustment" before

starting this adjustment.

[1] If SP245 is set to 1, change it to 0, and turn the NC power ON again. If it is already set to 0, go

to step [2].

[2] If the SP245 setting is 0, change it to 1.

[3] Input forward run start. The spindle motor will automatically rotate at the adjustment speed

(two stages for offset adjustment and gain adjustment). (The control input 3/bit8 or bit9 is

changed to 1 after the forward run start input, and "D" is displayed for the drive unit until

automatic adjustment is completed. For C1-SPM, a control output 4/bitD status of 1 is

established on the NC spindle monitor screen from startup until a restart occurs.)

[4] The adjustment results will be calculated and the operation will automatically stop several

seconds after forward run is started. (When automatic adjustment is completed, the drive unit

display at the NC spindle monitor screen changes from "D" to "C". Even though the motor is

stopped while "D" is displayed, automatic adjustment is in progress. Be sure to wait until "C"

displays.)

[5] Turn forward run OFF. (The adjustment data will be saved.)

[6] Turn the NC power ON again.

After completing the PLG adjustment, carry out trial operation, and confirm that there is no abnormal

noise (knocking or scratching noise) during forward run or reverse run.
