A.042:
Parameter
Combination Error
The speed of program JOG oper-
ation is lower than the setting
range after changing the elec-
tronic gear ratio (PnA42/PnA44)
or the servomotor.
Check if the detection conditions
*1
are satisfied.
Decrease the gear ratio (PnA42/
PnA44).
The speed of program JOG oper-
ation is lower than the setting
range after having changed the
setting of the program JOG
movement speed (Pn533).
Check if the detection conditions
*1
are satisfied.
Increase the setting of the program
JOG movement speed (Pn533).
The travel speed for advanced
autotuning is lower than the set-
ting range after changing the
electronic gear ratio (PnA42/
PnA44) or the servomotor.
Check if the detection conditions
*2
are satisfied.
Decrease the gear ratio (PnA42/
PnA44).
A.050:
Combination Error
(The SERVOPACK
and servomotor
capacities do not
correspond.)
The SERVOPACK and servomo-
tor capacities do not match each
other.
Check the capacities to see if they
satisfy the following condition:
Select the proper combination of
SERVOPACK and servomotor
capacities.
An encoder fault occurred.
Replace the servomotor and see if
the alarm occurs again.
Replace the servomotor (encoder).
A.051:
Unsupported Device
Alarm
An unsupported encoder is con-
nected to the SERVOPACK.
Check the product specifications,
and select the correct model.
Select the correct combination of
units.
A.0b0:
Cancelled Servo ON
Command Alarm
After executing the utility func-
tion to turn ON the power to the
motor, the servo ON command
(SV_ON) was sent from the host
controller.
−
Restart the SERVOPACK or exe-
cute a software reset.
