■2. Precautions for test operations
The following describes the precautions when performing a test operation of the servo amplifier monitor.
Do not operate the servo amplifier switches with wet hands. Doing so can cause an electric shock.
Do not perform operations with the front cover of the servo amplifier removed. Doing so can cause an electric shock
since the high-voltage terminals and live parts are exposed.
Do not open the front cover of the servo amplifier when the power is on or during operation. Doing so can cause an
electric shock.
Be sure to read the precautions for test operation in the manuals of the servo amplifier before performing a test
operation.
Check parameters of the servo amplifier before starting operation. Unexpected operations may occur depending on
the machine.
T The heat sink, regenerative brake resistor, servo motor and other parts of the servo amplifier may be hot while the
power is on or for a period after the power is turned off; therefore, do not touch or bring parts (cables etc.) close to
them. Doing so can cause fire or damage to the parts.
(1) Servo on
For test operation of JOG operation/positioning operation, the SON digital input signal of the servo amplifier is turned
on automatically in the servo amplifier to start operation, regardless of the ON/OFF status of the SON signal of the
digital I/O signal of the servo amplifier.
In addition, the servo amplifier does not accept any external command pulses and input signals (excluding
emergency stop) until the test operation screen is exited.
The SON automatically turns on when touching the [Forward] key or [Reverse] key on the JOG operation screen or
positioning operation screen of the servo amplifier monitor.
(2) Stop
To perform an emergency stop, turn off the emergency stop signal of the servo amplifier or turn off the input power.
(a) Use the following procedure to stop test operation from the servo amplifier monitor.
• JOG operation
Release the [Forward] key or [Reverse] key.
• Positioning operation
Touch the [Pause] key.
(b) The servo motor stops if any of the following states occurs during test operation.
• The communication cable is disconnected.
• The screen is switched to another servo amplifier monitor screen or the servo amplifier monitor is exited.
However, during motor-less operation, the test mode is not canceled until the servo amplifier is powered off.
■3. Preparations for test operations
When performing test operations, it is necessary to make the test operation settings on the connected servo amplifier.
Refer to the manual of the connected servo amplifier for details of making settings on the servo amplifier to perform test
operations.
