The following only applies to Inverters with SPEC: E or later.
The operation after starting or stopping depends on the setting of b1-05 when flux vector control is selected
(A1-02 = 3).

Setting Precautions
When using flux vector control, the zero-speed control starts when motor speed drops to b2-01 during
•
deceleration. Also, the setting b2-01 < E1-09 is possible.
The current level during injection brake time at start is the value of E2-03 (motor no-load current). Accord-
•
ingly, b2-02 is invalid in flux vector control.
