Mitsubishi Electronics MR-J2S- CL Alarm history clear, Software limit, Parameters, Description

5. PARAMETERS

5.2.5 Changing the stop pattern using a limit switch

The servo amplifier is factory-set to make a sudden stop when the limit switch or software limit is made valid. When a sudden stop is not required, e.g. when there is an allowance from the limit switch installation position to the permissible moving range of the machine, a slow stop may be selected by changing the parameter No.22 setting.

Parameter No. 22 setting	Description
0(initial value)	Droop pulses are reset to make a stop. (Sudden stop)
1	Droop pulses are drawn out to make a slow stop. (Slow stop)

5.2.6 Alarm history clear

The alarm history can be confirmed by using the Set-up Software or communication function. The servo amplifier stores one current alarm and five past alarms from when its power is switched on first. To control alarms which will occur during operation, clear the alarm history using parameter No.16 (alarm

history clear) before starting operation. Clearing the alarm history automatically returns to “ 0 ”. This parameter is made valid by switching power off, then on after setting.

Parameter No. 16

Alarm history clear 0: Invalid (not cleared)

1: Valid (cleared)

5.2.7 Software limit

A limit stop using a software limit is made as in stroke end operation. When a motion goes beyond the setting range, the motor is stopped and servo-locked. This function is made valid at power-on but made invalid during home position return. This function is made invalid when the software limit setting is the same as the software limit setting. A parameter error (AL. 37) will occur if the software limit setting is less than the software limit setting.
