(5) The value of Torque Boost
V
oltage (3004-0A hex, 3009-06
hex) is too high.
Check and readjust the value of
Torque Boost Voltage (3004-0A
hex, 3009-06 hex) so that lower-
ing the value does not cause a
stall.
→ Adjust the value of Torque
Boost Voltage (3004-0A hex,
3009-06 hex).
Set the value of Torque Boost
Voltage (3004-0A hex, 3009-06
hex) appropriately.

Cause and
correction
Assumed cause Correction Prevention
(1) The characteristics of the
electronic thermal and the over-
load characteristics of the motor
do not match.
Check the motor characteristics.
→ Review the values of 2nd
Motor Electronic Thermal
Characteristic selection
(3009-07 hex) and 2nd Motor
Electronic Thermal T
ime
Constant
(3009-09 hex).
→ Use an external thermal relay.
Set the parameters according to
the motor characteristics.
(2) The operation level of the
electronic thermal is not appro-
priate.
Recheck the motor’s continuous
allowable current.
→ Review and change the value
of 2nd Motor Electronic
Thermal Level (3009-08 hex).
Set the electronic thermal’s oper-
ation level appropriately.
(3) The acceleration/deceleration
time is short.
Recalculate the required acceler-
ation/deceleration torque and ac-
celeration/deceleration time
based on the load’s moment of
inertia and acceleration/decelera-
tion time.
→ Increase the values of
2nd
Acceleration Time 1 (3005-0B
hex), 2nd Acceleration Time 2
(3005-0F hex), 2nd
Deceleration Time 1 (3005-0C
hex), and 2nd Deceleration
Time 2 (3005-10 hex).
Set the acceleration/deceleration
time as long as possible to re-
duce the load. Or set a longer
stop time to reduce the load.
