Concept Inverter Control for Energy Saving Wire and Space Saving Easy Operation and Maintenance Optimum for Fan and Pump Applications Model Configuration

Enhanced PID control

Water-cooling pump for a showcase

· To save energy in low-speed operation : PID output shutoff (sleep) function

· To shorten the start-up time of PID control : PID automatic switchover function

· For air conditioning applications : Forward/reverse rotation switching by external signals

· To use various types of detectors : PID set point and measured value outputs in voltage (0 to 5V / 0 to 10V) and current (4 to 20mA)

Regeneration avoidance function

· The operation frequency is automatically increased to prevent the regenerative overvoltage fault from occurring. This function is useful when a load is forcibly rotated by another fan in the duct.

Automatic restart after instantaneous power failure function / flying start function

After an instantaneous power failure, the operation is re-startable from the coasting motor speed.
Even if the rotation direction has been forcibly reversed, the operation can be smoothly restarted in the original direction.

The fan is rotated by the external force.
