Servo alarm: Turns OFF when an error is detected. 5.5.1
/TGON+
/TGON- 27

Detection during servomotor rotation: detects
whether the servomotor is rotating at a speed higher
than the motor speed setting. Motor speed detection
can be set via parameter.

Speed coincidence (output in Speed Control Mode):
detects whether the motor speed is within the
setting range and if it matches the reference speed
value.
5.5.4
Position
/COIN+
/COIN- 25
26
Positioning completed (output in Position Control
Mode): turns ON when the number of error pulses
reaches the value set. The setting is the number of
error pulses set in reference units (input pulse units
defined by the electronic gear).

Note: 1. Pin numbers in parenthesis () indicate signal grounds.
2. The functions allocated to /TGON, /S-RDY, and /V-CMP (/COIN) can be changed via parameters.
Functions /CLT, /VCT, /BK, /WARN, and /NEAR signals can also be changed. (See 5.3.4 Output
Circuit Signal Allocation).
