cation Error
Cause
2 .
- Load GD is too big
- When there is regeneration
resistor, regeneration resistor
is open.
- Error in encoder connection or
connector
- No attached encoder
- Encoder input part B'D error
- Pulse error, which exceeds
user parameter SEt-33.
- Gain is too low.
- External load is too big.
Low voltage of external battery
of absolute encoder
Internal main capacitor of
absolute encoder is low voltage
- When encoder power wire is
not connected
- SEt-51 setting error
- Encoder error
In case of which main power is
not supplied in the encoder,
motor axis rotates in high
speed. In such case, there may
be an error in multi rotation
data of absolute encoder.
- Error occurred in current
feedback inside the servo
- Motor error
- Momentary black out occurs
during the operation
- Control power is cut off from
the exterior
EEPROM data error inside the
servo
Data which has gone off the
user setting limit is recorded.
Not fit to motor and encoder
type
Communication error occurs by
noise.
Corrective Action
- Check load inertia
- Check motor connection
- Check regeneration resistor is
open and increase regeneration
resistor capacity
- Check CN2 connection status
- Turn OFF and reset alarm
- Check pulse input part connection
status
- Lower the input frequency
- Raise Feed Forward gain of SEt-34.
- Raise speed gain (SEt-2,3).
- Raise position gain (SEt-4).
Battery exchange
Check encoder cable
Reference)
Motor continues to operate even if
the alarm is displayed.
In the status where the power has
been connected, after about 1
minute, reset with operator or I/O.
Here, multi rotation data of absolute
encoder is also set as 0.
- Check encoder power line
- SEt-51 check
- Encoder exchange
Multi rotation data is reset to 0
when resetting with operator or I/O.
- Check motor status
- Ask for A/S
Eliminate momentary blackout
function of user parameter SEt-43.
Operate parameter initialization in
USr-09 and check the motor
capacity and encoder type. And re-
distribute the power.
* When initializing the data when
ALARM E.80 occurs, all user
parameter values change to initial
setting value. In this case, the
system can be operated normally
if the setting is checked and reset
properly without initialization.
Reset SEt-51,SEt-52,SEt-53.
Un-attach and re-attach the
operator.
