| H18 | Torque control |
Instantaneous switching to another power line (when the power of an operating motor is cut off or power failure occurs) creates a large phase difference between the line voltage and the voltage remaining in the motor, which may cause electrical or mechanical failure. To rapidly switch power lines, write the remaining voltage attenuation time to wait for the voltage remaining in the motor to attenuate. This function operates at restart after a momentary power failure.

When the momentary power failure time is shorter than the wait time value, a restart occurs following the wait time. When the power failure time is longer than the wait time value, a restart occurs when the inverter is ready to operate (after about 0.2 to 0.5 second).

This function determines the reduction rate of the output frequency for synchronizing the inverter output frequency and the motor speed. This function is also used to reduce the frequency and thereby prevent stalling under a heavy load during normal operation.
| H | 4 | F | A | L | L |
| R | A | T | E |
|
| Setting range: | 0.00, 0.01 to 100.00 Hz/s |
When 0.00 is set, the frequency is reduced according to the set deceleration time.
Note:
A too large frequency reduction rate is may temporarily increase the regeneration energy from the load and invoke the overvoltage protective function. Conversely, a rate that is too small extends the operation time of the current limiting function and may invoke the inverter overload protective function.

When power supply voltage to the inverter is high, control can be stabilized even under an excessive load by raising the operation continuation level. However, when the level is too high, this function activates during normal operation and causes unexpected motion. Please contact Fuji electric when changing the initial
value. |

As the power to an external operation circuit (relay sequence) and the main power to the inverter is generally cut off at a power failure, the operation command issued to the inverter is also cut off. This function sets the time an operation command is to be held in the inverter. If a power failure lasts beyond the

When "999" is set, an operation command is held (i.e., considered a momentary power failure) while control power in the inverter is being established or until the main circuit DC voltage is about 100Vdc.

The torque command value is +200% when the voltage at terminal 12 is +10V and is
function.
In torque control, the torque command value and motor load determine the speed and direction of rotation.
When the torque is controlled, the upper limit of frequency refers to the minimum value among the maximum frequency , the frequency limiter (upper limiter) value, and 120 Hz. Maintain the frequency at least
If the operation command goes off during a torque control operation, the operation is switched to speed control and the motor
