5.6 Signal for safety

This section explains the functions and input/output signals for safety operation contained in amplifier.

5.6.1 Forced stop [EMG]/Forced stop detection

Stops the motor forcibly using the signal to control input terminal.
Forced stop [EMG]/Forced stop detection (Control input / output signal)
■ Function
(1) Forced stop [EMG]
While the [EMG] (10) signal is off, the motor is forced stopped.
This input signal is always valid in any control made, and has the highest priority (all other commands are ignored.).
Connect the [EMG] (10) signal directly to the control input terminal of amplifier because the safe operation and speed detecting are
important.
Normally, connect this terminal to a push-lock type (NC contact) pushbutton switch (Fuji's command switch is recommended).

(2) Forced stop detection

When the [EMG] (10) signal is turned off, the forced stop detection (41) signal is turned on, to be informed the current status externally.
However, the forced stop detection (41) signal is turned off, while external fault input (34) is off.
・Basic type (D/DO position)
At factory setting, the forced stop signal is allocated to CONT13 terminal (Pin 20 of CN3).
・SX bus type (SX bus direct connection)
At factory setting, the [EMG] signal is not allocated to the control input terminal of CN1. Allocate this signal to use it.
When allocated to IQ area, bit ON executes the forced stop.
・T-link type (T-link direct connection)
At factory setting, the [EMG] signal is not allocated to the control input terminal of CN1. Allocate this signal to use it.
When allocated to WB area (at bit 5 in word +4 position), bit on executes the forced stop.
■ Parameter setting
To allocate the [EMG] signal to the control input terminal, set (10) to the system para.. If this signal is not allocated to the control input
terminal, this signal is deemed "always on".
To allocate the forced stop detection signal, set (41).
The [EMG] signal can be allocated to multiple terminals, and when any of those input signals is on, the motor stops forcibly.
■ Related item
(1) Ready [RDY]
After the [EMG] (10) signal is allocated to the control terminal, when the ready [RDY] signal is turned on with both the run command [RUN]
(3) and the [EMG] signals on, the motor can rotate.
(2) Forced stop status
While the [EMG] (10) signal is off and the [RUN] is on, the motor makes a stop in the speed zero status making the speed command is zero.
Current position cannot be retained in the speed zero status. As the current position has been stored, the origin return action is not
necessary again when the [EMG] signal is off. Turning on the [EMG] signal allows the motor to rotate.
If the [RUN] signal is off while the [EMG] is off, the motor is in free-run status.
(3) Rotation command
While the [EMG] signal is off, all of the rotation commands are ignored.
When the alarm reset signal is on, or condition of the [EMG] signal is not needed.
