LNC-M600 Leading Numerical Controller Maintenance Manual

LNC-M600
Parameter
185 FEEDBACK DIR OF SERVO AXES(BIT)
Range: 0 ~ 63
Active: Active After Reboot
Level: Machinery Builder
Default 0
value:
Unit: Nul
Description BIT0:when set as 1, means negative X-axis ENCODER feedback signal
:
BIT1:when set as 1, means negative Y-axis ENCODER feedback signal BIT2:
when set as 1, means negative Z-axis ENCODER feedback signal
BIT3:when set as 1, means negative 4 TH -axis ENCODER feedback signal
BIT4:when set as 1, means negative spindle ENCODER feedback signal
【Setting timing】
Take X-axis for example, if X-axis is set as PULSE TYPE, when you press the
+X button of OP panel, the machine X-axis moves in positive direction, but the
value of system data #000(X-axis following error) continuously increases, and
this value doesn’t decrease down to the range of ±1, it means that you have to
reverse the X-axis ENCODER signal.
(Usually this is caused when the BIT0 of parameter # 0116 is set as 1.) In this
case, please set the BIT0 of parameter # 0116 as 1. If the above didn’t occur,
please set the BIT0 of parameter # 0116 as 0. If X-axis is under V COMMAND
mode, when you press the +X button of OP panel, the machine X-axis rushes, it
means that you have to reverse the X-axis ENCODER signal. In this case,
please set the BIT0 of this parameter as1.
So is the same with all the other axis.
188 POSITION LOOP GAN OF EACH AXIS
Range: 1 ~ 32767
Active: Active After RESET
Level: Machinery Builder
Default 30
value:
Unit: 1/sec
Description This parameter is to calculate and make sure that the contour error remain with
:
the tolerance via arch feedrate auto clamp function. (please refer to Parameter
# 0187). Under PULSE TYPE, since servo driver deals with position control
loop, NC system is not able to know this set value. If you want to enable the
arch feedrate auto clamp function, you have to set a position loop gain in your
formula. Notice that the position loop gain of each axis must be the same
otherwise the actual contour of the arch command will become ellipse.
Please refer to related parameters (#0187 and # 0809).
