CHAPTER 3 OPERATION

3.1 Signal Description (Priority among Input Signals)

Input signals of the servo amplifier for stopping the motor shaft are received first in view of safety.

Description

01 Operation signal always given highest priority

02 Operation signal always given priority

03 Signal for controlling the torque

04 Signal for stopping the motor

05 Signal for turning the motor

06 Signal for determining the home position

07 Signal irrelevant to motor operation

Applicable signal

(Function No.)

 Free-run command (54)

 Servo-on (1)

 Forced stop (10)

 External regenerative resistor overheat (34)

 Torque limit 0 (19)

 Torque limit 1 (20)

 +OT (7)

 -OT (8)

 Command pulse inhibit (26)

 Pause (31)

 Positioning cancel (32)

 Deviation clear (50)

 Forward rotation (2)

 Reverse rotation (3)

 Start positioning (4)

 Homing (5)

 Home position LS (6)

 +OT (7)

 -OT (8)

 Interrupt input (49)

 Position preset (16)

 Alarm reset (11)

 Edit permission (55)

 The moving part of the mechanical system of the elevator may drop if a free-run command is

used. Do not assign the command unless necessary.

 If +OT (7) is detected during rotation caused by a forward rotation (2) signal, priority is given to the

+OT (7) signal.

Even if the +OT (7) signal is detected, priority is given to the torque limit 0 and 1 (19 and 20)

signal.

Priority is given to forced stop (10) during operation with a torque limit 0 and 1 (19 and 20) signal.

However, if the free-run command (54) signal is issued, the servo amplifier output is stopped.

 The response time of the sequence input terminal and output terminal is about 1 ms.

If the zero deviation signal setting or similar is too small, the host PLC may fail to recognize.

(The scanning cycle of a general PLC is several tens of milliseconds [ms].)
