Clear multiturn position
Before clearing multiturn position, axis needs to be homed. After clearing multiturn
position, revolution count = 0 but absolute position remains unchanged and Err153 alarm
will be cleared.
Please make sure the homing point is within the range of 1 revolution of the rotor.
Installation and setup of the homing point can be set with the use of auxiliary function
D21 on the front panel.
By setting Pr0.15 to 9, multiturn position will be cleared.
Please take notice of motor position during power on. Range of motion of a motor
depends on the position of the motor during power on (23-bit absolute encoder as
example).
