6.2 Run Command Tuning
6.2.1 Run Command Minimum ON Time Function
The Run command is hold during minimum ON Time (S2-01,-02).
Operation Description:
(1) Entering a Run Command when the drive is stopped (for all Control Modes):
(a) If the time for the Run Command to be entered is shorter than the minimum "on-time" (S2-01, -02), then only the
minimum "on-time" will be maintained by the drive internally.
(b) If the time for the Run Command to be entered is longer than the minimum "on-time" (S2-01, -02), then the drive
will maintain the Run Command internally for the time taken to enter the Run Command.
(2) Entering a Run Command while Decelerating to Stop
(a) When both the output frequency and a Run Command in either direction are entered, then the drive will operate as
shown below, regardless of the control mode.
Minimum ON Time (S2-01, -02) = 0 Minimum ON Time (S2-01, -02) ? 0
Run Cmd ON
Conditions
Control Mode
Output Frequency > Fa Output Frequency = Fa Output Frequency > Fa Output Frequency = Fa
All Control Modes re-accelerates brief stop (stops for a minimum of 50ms)
(b) If the output frequency and a REV Run Command is entered, then the drive will operate as follows:
When in Flux Vector Control Mode during deceleration at a frequency higher than Fa, if the minimum “on-time”
setting is zero as a Run Command is given on the REV side, then the drive will run (FWD/REV) without braking.
Minimum ON Time (S2-01, -02) = 0 Minimum ON Time (S2-01, -02) ? 0
Run Cmd ON
Conditions
Control Mode
Output Frequency > Fa Output Frequency = Fa Output Frequency > Fa Output Frequency = Fa
Flux Vector Control Mode
Brake is not applied, and
FWD/REV switching is
activated.

Not Flux Vector Control Mode
Note: Fa is the larger of either the Brake Release Frequency (S1-01, or S1-02 when in reverse) or the Brake
Release Frequency (S1-12, or S1-13 when in reverse).
