Product information

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 frequency: 100kHz)

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.

The inverter protects the braking resistor by monitoring the braking transistor operation. The inverter outputs a dedicated signal for the detection of the braking transistor failure. A circuit for shutting off the input power supply must be provided outside of the inverter. When this signal is output, the power is shut off; thus protecting the braking circuit.

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.

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.

(1) Analog inputs: voltage input through 2 terminals with polarity, current input through 1 terminal (2) Slow flowrate level stop function (Pressurized operation is possible before slow flowrate operation stop.) (3) Non-linear V/f pattern at 3 points (4) Dummy failure output function (5) Selection of 4 motors (6) S-shape accel./decel. range setting (7) Detecting disconnection of the PID feedback

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 loop (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 customizable logic function is adopted in the inverter body.

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 holds the current position of the motor shaft when motor is stopped under vector control with speed sensor. This function is useful when torque is applied externally or holding torque is required during the stop time.
