If the Motor Does Not Put Out Torque or If Acceleration is Slow

„
The stall prevention level during acceleration is too low.
If the value set for L3-02 (Stall Prevention Level during Acceleration) is too low, the acceleration time will be
too long. Check to be sure that the set value is suitable.
„
The stall prevention level during running is too low.
If the value set for L3-06 (Stall Prevention Level during Running) is too low, the speed will drop before out-
putting torque. Check to be sure that the set value is suitable.

If the Motor Operates Higher Than the Reference

Use the following information if the motor operates on a higher level than the reference.
„
The analog frequency reference bias setting is wrong (the gain setting is wrong).
The frequency reference bias set in parameter H3-03 is added to the frequency reference. Check to be sure that
the set value is suitable.
„
A signal is being input to the frequency reference (current) terminal A1.
When 1F (frequency reference) is set for parameter H3-09 (Multi-function Analog Input Terminal A2 Func-
tion Selection), a frequency corresponding to the terminal A2 input voltage (current) is added to the frequency
reference. Check to be sure that the set value and analog input value are suitable.

If Motor Deceleration is Slow

Use the following information when the motor deceleration is slow.
„
The deceleration time is long even when braking resistor unit and braking unit is con-
nected.
The following causes are possible.
"Stall prevention during deceleration enabled" is set.
When Braking Resistor Unit and Braking Unit is connected, set parameter L3-04 (Stall Prevention Selection
during Deceleration) to 0 (disabled). When this parameter is set to 1 (enabled, the factory setting), braking
resistor unit and the braking unit do not fully function.
The deceleration time setting is too long.
Check the deceleration time setting (parameters C1-02 and C1-04).
Motor torque is insufficient.
If the parameters are correct and there is no overvoltage fault, then the motor's power is limited. Consider
increasing the motor capacity.
