HUST CNC H6D-T Manual
7 - 32
If a homing process with C64-69 is planned in PLC, it shall be based on
the activity set by PLC.
MCM# 430~440 System Reserved
441. Direction of Motor Rotation, X-axis.
442. Direction of Motor Rotation, Y-axis.
443. Direction of Motor Rotation, Z-axis.
444. Direction of Motor Rotation, A-axis.
445. Direction of Motor Rotation, B-axis.
446. Direction of Motor Rotation, C-axis.
447. Direction of Motor Rotation, U-axis.
448. Direction of Motor Rotation, V-axis.
449. Direction of Motor Rotation, W-axis.
Format (Default=0)
Setting = 0, Motor rotates in the positive direction. (CW)
Setting = 1, Motor rotates in the negative direction. (CCW)
This MCM can be used to reverse the direction of motor rotation if desired. So
you don’t have to worry about the direction of rotation when installing motor.
These parameters will affect the direction of HOME position
IMPORTANT: Motor Divergence
Due to the variations in circuit design of the servo drivers that are available from
the market, the proper electrical connections from servo encoder to the driver,
then to the CNC controller may vary. If the connections do not match properly,
the motor RPM may become divergent (Rotate @ HIGH RPM) and damage to
the machine may result. For this reason, HUST strongly suggest separate the
servo motor and the machine before you are 100% sure the direction of the
motor rotation. If a motor divergence occurs, please inter-change the connections
of (A and B phase) and (A- and B- phase) on the driver side.
(This statement has nothing to do with MCM #154~ #157 but it’s very important
when connecting electrical motor.)
If a motor divergence occurs, please inter-change the connections of (A and B
phase) and (A- and B- phase) on the driver side.
