z Select the inverter control system such as speed control, torque control or position control.
z If "9" is set in Pr. 800, speed control test operation can be performed even when the motor is not connected.
The speed calculation value changes to track the speed command and the transition can be checked with the
control panel and analog signal output at DA1 and DA2.
z Refer to page 47 for details.

CAUTION
• When supplying power only across R1-S1, E.OC1 (overcurrent at acceleration) occurrs when the start signal turns on.
• Since current is not detected and voltage is not output, monitors related to current and voltage such as output current and
output voltage, etc. and output signals do not function.
• For speed calcuration, speed is calculated in consideration of Pr. 880 "load inertia ratio".
