(Supplement to Instruction Manual)
(1) Online tuning
Performs tuning while the motor is rotating in order to cover the motor speed
fluctuation caused by the temperature rise of the motor.
(2) Function extension of brake signal
Extends the brake-ON sequence function.
(3) PG error processing
Changes the PG error detection width if the speed command exceeds the base
frequency.
(4) Synchronous operation
Enables synchronous operation of two motors equipped with a pulse generator
(PG). The PG interface card (OPC-G1-PG or OPC-G1-PG22) is required. For
details, refer to the PG Interface Card Instruction Manual.
(5) Motor magnetic flux weakening control under "vector control without speed
sensor"
Improves the torque control stability. The overspeed detection level can be
specified.
(6) Improved regenerative power control under vector control
Adjusts the motor magnetic flux level to be applied during deceleration under
vector control.
(7) Terminal command "Enable battery operation" BATRY
(Function code data = 59)
Cancels the undervoltage protection so that the inverter under an undervoltage
condition runs the motor with battery power.
(8) "0 to 20 mA" range added to analog input/output
(9) Speed limit level adjustable with analog inputs under torque control
