Accommodating various applications

Convenient function for operations at the specified speed
The pulse train input function is equipped as standard.
It is possible to issue the speed command with the pulse train input (single-phase pulse and a sign of command value) from the pulse generator, etc.
(Maximum pulse input: 100kHz)
 
Convenient function for operations at the specified speed
 
Ratio operation
The ratio operation is the function particularly convenient for adjusting two or more conveyance systems. The ratio of the main axis speed to the two or more trailing axes can be set as a frequency command. On the machine that handles load variation such as a conveyance machine, the conveyance speed can be adjusted easily.
 
Convenient function for operations at the specified speed
Thorough protection of the braking circuit
The inverter protects the braking resistor by monitoring the braking transistor operation. The inverter outputs an exclusive signal on detection of the braking transistor abnormality. A circuit for shutting off the input power supply is provided outside of the inverter. When this signal is output, the power is shut off; thus protecting the braking circuit.
Optium function for preventing an object from slipping down
The reliability of the brake signal was increased for uses such as vertical conveyance. Conventionally, the current value and the frequency have been monitored when the brake signal is output. By adding a torque value to these two values, the brake timing can be adjusted more easily.
 
Optimum function for preventing an object from slipping down
Dancer control function optimum for winding control
The PID value, calculated by comparing the target value and the feedback value, is added to or subtracted from the reference speed. Since the PID calculator gain (in proportional range) can be set to a low value, the inverter can be applied to the automatic control system that requires quick response such as a speed controller.

PG option card for positioning control  
   
This control function is best suited for the application that requires highly accurate positioning such as that of the conveyance machine. By combined use of the position control device (APR) and PG vector control, the position control accuracy has been remarkably improved. Shortened positioning time by this function will be helpful to reduce the tact time of a cycle.

The customized logic interface function is adopted in the inverter body. (Available soon)
 
Logic input/output can be easily created by parameter setting. This makes it possible to simplify the peripheral circuits.

Introducing servo lock function (PG option card).
This function is effective in adjusting the stop timing or the braking torque when the equipment such as a conveyance machine is stopped by positioning of the motor. This function is helpful when torque is applied externally or holding torque is required during the stop time. The tact time per cycle will be reduced by shortened deceleration time.
