[Al. 561_Safety Speed Monitor Error 1 (Safety Sub-Function)] - Mitsubishi Electric MR-J5-G Series User Manual

[AL. 561_Safety speed monitor error 1 (safety sub-function)]

• The safety sub-function detected an error of the servo motor speed.
[AL. 561.1_SLS1 feedback speed exceeded A]
Cause
1.
The state where the absolute value of the
servo motor speed exceeds the setting value
of [Pr. PSA11 SLS speed 1] continued for the
time set in [Pr. PSA15 Safety sub-function -
Speed detection delay time] or longer during
operation of the SLS function.
2.
The settings of the electronic gear are
incorrect.
3.
The servo system is unstable and oscillating.
4.
The velocity waveform overshot.
5.
The connection destination of the encoder
cable is incorrect.
6.
The encoder has malfunctioned.
[AL. 561.2_SLS1 command speed exceeded A]
Cause
1.
The state where the absolute value of the
speed command exceeds the setting value of
[Pr. PSA11 SLS speed 1] continued for the
time set in [Pr. PSA15 Safety sub-function -
Speed detection delay time] or longer during
operation of the SLS function.
2.
Take actions according to the instructions of 5. to 6. in the following item.
Page 176 [AL. 561.1_SLS1 feedback speed exceeded A]
[AL. 561.3_SLS2 feedback speed exceeded A]
Cause
1.
The state where the absolute value of the
servo motor speed exceeds the setting value
of [Pr. PSA12 SLS speed 2] continued for the
time set in [Pr. PSA15 Safety sub-function -
Speed detection delay time] or longer during
operation of the SLS function.
2.
Take actions according to the instructions of 2. to 6. in the following item.

1.3 Handling methods for alarms/warnings
Check/action method
Review the parameter or the operation pattern.
Take actions such as setting the speed command to a value equal to or lower
than the value of [Pr. PSA11] or setting the time required for deceleration in
[Pr. PSA07 SLS deceleration monitor time 1].
Refer to "SLS function" in the following manual.
MR-J5 User's Manual (Function)
Check the setting value of the electronic gear.
Refer to "Electronic gear function" in the following manual.
MR-J5 User's Manual (Function)
Adjust the servo gain or reduce the load.
Increase the acceleration/deceleration time constants.
Check the connection destination of the encoder.
Replace the servo motor.
Check/action method
Review the parameter or the operation pattern.
Take actions such as setting the speed command to a value equal to or lower
than the value of [Pr. PSA11] or setting [Pr. PSA15] to a longer value.
If in torque control, set the speed limit to a value equal to or lower than the
value of [Pr. PSA11].
Refer to "SLS function" in the following manual.
