released. In order
to improve the zero return precision, and it should ensure the motor reaches the one-turn
signal of
encoder after it rotates half circle.
The parameter setting is as follows:
Bit parameter No.004 BIT5(DECI) =0
Bit parameter No.006 BIT0(ZMX) , BIT1(ZMZ) , BIT2(ZMY), BIT3(ZM4), BIT4(ZM5) =0
Bit parameter No.007 BIT0(ZCX) , BIT1(ZCZ) , BIT2(ZCY) , BIT3(ZC4), BIT4(ZC5)=0
Bit parameter No.011 BIT2(ZNLK) =1
Bit parameter No.014 BIT0(ZRSCX) , BIT1(ZRSCZ) , BIT2(ZRSCY), BIT3(ZRSC4),
BIT4(ZRSC5) =1
Data parameter No.033=200
Data parameter No.183 BIT0(MZRX) , BIT1(MZRZ) , BIT2(MZRY), BIT3(MZR4) ,
BIT4(MZR5)
=0

When matching the stepper motor, it is better to adjust the rapid override to 50% to avoid
the
out-of-step during rapid traversing of zero return, so the parameter settings are as follows:
Bit parameter No.004 BIT5(DECI) =0
Bit parameter No.006 BIT0(ZMX) , BIT1(ZMZ) , BIT2(ZMY), BIT3(ZM4), BIT4(ZM5) =0
Bit parameter No.007 BIT0(ZCX) , BIT1(ZCZ) , BIT2(ZCY), BIT3(ZC4), BIT4(ZC5) =1
Bit parameter No.011 BIT2(ZNLK) =0
Bit parameter No.014 BIT0(ZRSCX) , BIT1(ZRSCZ) , BIT2(ZRSCY), BIT3(ZRSC4),
BIT4(ZRSC5)
=1
Data parameter No.033=200
Data parameter No.183 BIT0(MZRX), BIT1(MZRZ), BIT2(MZRY), BIT3(MZR4),
BIT4(MZR5) =0
BIT０～BIT４of diagnosis message DGN.000 are used to check the validity of zero
deceleration
signal.
4.6 Spindle Adjustment
4.6.1 Spindle encoder
Encoder with the pulses 100~5000p/r is needed to be installed on the machine for
threading. The
pulses are set by data parameter No.70. The transmission ratio(spindle gear
teeth/encoder gear teeth)
