Test operation mode Operation
MELSERVO J2-Super 4 - 9
● Motor-less operation
Without connecting the servo motor, output signals or status displays can be provided in
response to the servo system controller commands as if the servo motor is actually running. This
operation may be used to check the servo system controller sequence. Use this operation with
the servo amplifier connected to the servo system controller.
Exercise control on the motor-less operation screen of the setup-software.
The following alarms and warning do not occur for operation without servo motor:
– Encoder error 1 (16)
– Encoder error 2 (20)
– Absolute position erasure (25)
– Battery cable breakage warning (92)
All other alarms and warnings occur as when the servo motor is connected
● Forced output signal
Output signals can be switched on/off forcibly independently of the servo status. Use this
function for output signal wiring check, etc.
Exercise control on the forced output screen of the setup-software.
NOTE
Motor-less operation may be used with the setup-software. However, use motor-less
operation which is available by making the servo system controller parameter setting.
