6.3.2 Setting the Zero-speed Operation Constants

D

With flux vector control, operation is possible even when the frequency reference is zero (below the
minimum output frequency).

D

Set the operation methods for the minimum output frequency.

J

Stopping Method Selection: b1-03

D

Set the stopping method used when a stop command is input.

Operate according to the frequency reference. (E1-09 is invalid.)

1

Interrupt the output. (Coast when the frequency reference is below E1-09.)

2

Operate at E1-09 frequency. (Output the frequency set in E1-09.)

3

Zero-speed operation (Zero reference value when the frequency reference is below E1-09.)

Minimum Output Frequency (FMIN): E1-09

D

Set the minimum output frequency according to the requirements of the application.
