9-4 Mode setup methods
[1] Mode 0
Stepping/servo motor system (both)
Wire the encoder.
Set the count direction for encoder input at parameter 2 - 0001.
When an electronic gear is used, set the ratio between the output pulse and encoder input pulse at
parameter 2 - 0030 to 0047. Electronic gear 1 (0030 to 0037) is the ratio setting for the instruction
system, and electronic gear 2 (0040 to 0047) is the ratio setting for the feedback system. (⇒ See
electronic-gear related setting restrictions.)
In this mode, operation is possible without using the electronic gear. In this case, the feedback
pulse becomes the instruction value as this is a direct signal that is input to the encoder.
Set parameter 2 - 0000 to "00" (BCD).
[2] Mode 1
(1) Stepping motor system
Wire the encoder.
Set the count direction for encoder input at parameter 2 - 0001.
When an electronic gear is used, set the ratio between the output pulse and encoder input pulse at
parameter 2 - 0030 to 0047. Electronic gear 1 (0030 to 0037) is the ratio setting for the instruction
system, and electronic gear 2 (0040 to 0047) is the ratio setting for the feedback system. (=> See
electronic-gear related setting restrictions.)
In this mode, the electronic gear must be set.
Set parameter 2 - 0000 to "01" (BCD).
Enter the number of allowable deviation pulses (number of output pulses - number of feedback
pulses) to be monitored during operation to the closed loop control allowable range of parameter
2 - 0004 to 0007.
Enter the number of allowable deviation pulses (number of output pulses - number of feedback
pulses) to be monitored at completion of operation to the completion pulse allowable range of
parameter 2 - 0010 to 0013.
(2) Servo motor system
Wire the encoder.
Set the count direction for encoder input at parameter 2 - 0001.
When an electronic gear is used, set the ratio between the output pulse and encoder input pulse at
parameter 2 - 0030 to 0047. Electronic gear 1 (0030 to 0037) is the ratio setting for the instruction
system, and electronic gear 2 (0040 to 0047) is the ratio setting for the feedback system. (=> See
electronic-gear related setting restrictions.)
In this mode, the electronic gear must be set.
Set parameter 2 - 0000 to "01" (BCD).
Enter the number of allowable deviation pulses (number of output pulses - number of feedback
pulses) to be monitored at completion of operation to the completion pulse allowable range of
parameter 2 - 0010 to 0013.
(Note) As the deviation during operation is monitored on the driver side, set the number of
allowable deviation pulses (parameter 2 - 0004 to 0007) to "0".
