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.

Setting Function
0
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.
