Basic Programming 5 - 6
When the output frequency has dropped below the DC Injection Start Frequency (b2-01) or the minimum output frequency
(E1-09) (whichever is greater), deceleration will stop and DC current will be injected into the motor at the current level set in
b2-02 for the time set in b2-04.
Fig 5.3 Deceleration to Stop
The actual deceleration time can be determined by the following formula:
1:Coast to stop: When the run command is removed, the Drive will turn off its output transistors. The friction of the driven
equipment will eventually overcome any residual inertia of the system and the motor will stop.
Fig 5.4 Coast to Stop
IMPORTANT
If S-Curve characteristics are set in the Drive programming, they will add to the total time to stop.
IMPORTANT
After a stop is initiated, subsequent run commands will be ignored until the Minimum Baseblock Time
(L2-03) has expired.
