[Al. 563_Deceleration Monitor Error (Safety Sub-Function)] - Mitsubishi Electric MR-J5-G Series User Manual

[AL. 563_Deceleration monitor error (safety sub-function)]

• There is a problem with deceleration operation in the safety sub-function.
[AL. 563.1_SS1 feedback speed exceeded A]
Cause
1.
The servo motor exceeded the observation
speed specified by [Pr. PSA24 SS1/SS2
deceleration monitor time constant] from the
observation speed when the SS1 command
was turned off during operation of the SS1
function.
2.
The connection destination of the encoder
cable is incorrect.
3.
There is a problem with the servo motor or the
servo motor power cable.
4.
The encoder has malfunctioned.
5.
The servo amplifier has malfunctioned.
6.
There is a problem with the surrounding
environment.
[AL. 563.2_SS1 command speed exceeded A]
Cause
1.
A speed command was input exceeding the
observation speed specified by [Pr. PSA24
SS1/SS2 deceleration monitor time constant]
from the observation speed when the SS1
command was turned off during operation of
the SS1 function.
2.
Take actions according to the instructions of 2. to 6. in the following item.
Page 180 [AL. 563.1_SS1 feedback speed exceeded A]
[AL. 563.3_SS2 feedback speed exceeded A]
Cause
1.
The servo motor exceeded the observation
speed specified by [Pr. PSA24 SS1/SS2
deceleration monitor time constant] from the
observation speed when the SS2 command
was turned off during operation of the SS2
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 a larger value in [Pr. PSA26 SS1/SS2
deceleration monitor delay time] or adjusting the servo gains.
Refer to "SS1 function" in the following manual.
MR-J5 User's Manual (Function)
Check the connection destination of the encoder.
Replace the servo motor or the servo motor power cable.
Replace the servo motor.
Replace the servo amplifier.
Check the noise, ambient temperature, and other conditions, and implement
appropriate countermeasures for the cause.
If there is noise, take countermeasures to reduce the noise.
Refer to "Noise reduction techniques" in the following manual.
MR-J5 User's Manual (Hardware)
Check/action method
Review the parameter or the operation pattern.
Take actions such as performing settings so that the time set in [Pr. PC24
Deceleration time constant at forced stop] becomes shorter than in [Pr. PSA24
SS1/SS2 deceleration monitor time constant].
Refer to "SS1 function" in the following manual.
MR-J5 User's Manual (Function)
Check/action method
Review the parameter or the operation pattern.
Take actions such as performing settings so that the deceleration command
from the controller does not exceed the deceleration monitor time constant,
setting a larger value in [Pr. PSA26 SS1/SS2 deceleration monitor delay time],
or adjusting the servo gains.
Refer to "SS2/SOS function" in the following manual.
