Torque limit is too low
check torque limit value
Adjust torque limit value correctly
Load inertia is too large
Calculate the ratio of load inertia and
rotor inertia
Reduce the load inertia or re-evaluate
the motor capacity

：
Brake Overload
Alarm
Causes
Check
Solution
Braking resistor is missed or
its capacity is too small
1
：
check the connection status of braking
resistor
2
：
Calculate the value of braking resistor
1
：
Reconnect the braking resistor
2
：
Use appropriate braking resistor
Load inertia is too large
Calculate if the ratio of load inertia and
rotor inertia is appropriate
Reduce load inertia or change the
motor with greater inertia
Improper parameters setting
1
：
check the
setting parameters of brake resistor
(P8-p18) and braking resistor capacity
(P8-20)
2
：
check if the deceleration time is too
short
1
：
Set the parameters of P8-p18 and
P8-20 properly
2
：
Increase the deceleration time

Solution
P-OT terminal is effective,
and command is forward
check the position of forward limit
switch
1
：
Release forward limit switch
2
：
Give reverse command
Servo system is unstable
check the setting value of control
parameter and load inertia
Re-correct control parameters or
re-evaluate the motor capacity

Solution
N-OT terminal is effective,
and command is reverse
check the position of reverse limit switch
1
：
Release reverse limit switch
2
：
Give the forward command
Servo system is unstable
check the setting value of control
parameter and load inertia
Re-correct control parameters or
re-evaluate the motor capacity
