A52900: Failure during data
copying
• Copying is halted.
• The micro SD card/SD card was
plugged out.
• The drive is not in the stop state.
• Re-plug in the micro SD card/SD card.
• Make sure the drive is in the stop state.
A52901: Braking resistor
reaches alarm threshold
The heat capacity reaches the threshold
(p29005) of the braking resistor capacity.
• Change the external braking resistor.
• Increase deceleration time.
A52902: Quick stop (EMGS)
missing
Implement servo on when the digital input
Switch on the digital input (EMGS) and then
For incremental encoder, when PTO fre-
quency exceeds 280K, drive will output
A52932 to remind that exceed limitation.
For absolute encoder, when PTO frequen-
cy exceeds 120K, drive will output A52932
to remind that exceed limitation.
Change PTO ratio.
