14.3.12 Spindle sequence I/O signals
 Comparison of spindle sequence signals
The following table shows comparison of the spindle sequence signals with the conventional
spindle sequence signals.
Name of conventional signal YS 840DI signal Specification
(relation to the conventional)
Remarks
Emergency Stop (EMG) None Main supply ON is common to the servo
drive.
Operation is Ready (RDY) DBB2.1 (Controller enable) Same as RDY
Servo Drive ON and Forward (FOR) DBX21.7 (Pulse enable) Same as the servo drive
Servo Drive ON and Reverse (REV) None Reverse command is for CNC function
P/Pi Control Switching (PPi) DBX21.6, DBX93.6
(controller integrator disable)
DBX21.6 is equal to PPi. DBX93.6 is
added to the completion check.
Also used for prevention of spindle
fluctuation. See section 14.3.13.
Orientation (ORT) None CNC function is enabled. See 14.3.13.
Orientation Completion (ORE)
Soft Start (SSC) None Automatically enabled with spindle con-
trol system.
Torque Limit (TLH, TLL) None Limit value is specified from CNC.
Torque Limit Enabled (TLE) None
Speed Agreement (SAGR) DBX94.6 (nact=nset) Equal to SAGR. ("1" for Speed agree-
ment)
See the parameters below.
Zero Speed detection (ZSPD) DBX94.4(|nact|<nmin) Equal to ZSPD. ("1" for the speed equal
or exceed setting value, "0" for the speed
less or equal to setting value)
See the parameters below.
Speed Detection (SDET) DBX94.5(|nact|<nx) Equal to SDET. ("0" for the speed equal
or exceed setting value, "1" for the speed
less or equal to setting value)
See the parameters below. Also see
14.3.14.
Load axis origin (ORG) None
Torque Detection (TDET) DBX94.3(Md<Mdx) Equal to TDET. ("0" for the speed equal
or exceed setting value, "1" for the speed
less or equal to setting value)
See the parameters below.
Fault (FLT) None CNC
Malfunction Warning None
