B-64120EN/01 4.DESCRIPTION OF PARAMETERS
- 107 -
NOTE
When an encoder with absolute address reference
marks (linear scale or rotary encoder) or encoder
with the absolute address zero point (linear scale
or rotary encoder) (detection circuit C) (closed loop
system) is used, set bit 1 (OPTx) of parameter No.
1815 to 1. When a linear scale with the absolute
address zero point (detection circuit C) (linear
motor system) is used, however, set OPTx to 0.
DCRx As an encoder with absolute address reference marks:
0 : A linear scale with absolute address reference marks is used.
1 : A rotary encoder with absolute address reference marks is used.
NOTE
1 Set bit 2 (DCLx) of parameter No. 1815 to 1.
2 When a rotary encoder with the absolute address
zero point (detection circuit C) is used, set this
parameter to 0.
APZx Machine position and position on absolute position detector when the
absolute position detector is used
0 : Not corresponding
1 : Corresponding
NOTE
When an absolute position detector is used, after
primary adjustment is performed or after the
absolute position detector is replaced, this
parameter must be set to 0, power must be turned
off and on, then manual reference position return
must be performed. This completes the positional
correspondence between the machine position and
the position on the absolute position detector, and
sets this parameter to 1 automatically.
APCx Position detector
0 : Other than absolute position detector
1 : Absolute position detector (absolute Pulsecoder)
For an absolute-position system using Inductosyn, set this
parameter to 1.
NRTx When the machine coordinate value on a rotation axis passes the
0-degree point or a point at which the machine coordinate value is
rounded off (360 degrees or the setting of parameter No. 1260):
0 : The zero point (parameter Nos. 1860 and 1861) is updated.
1 : The zero point (parameter Nos. 1860 and 1861) is not updated.
When a scale not maintaining speed data is used, set this parameter to
1.
