5. The system stability can be improved by incorporating derivative time Td properly (excessive
proportion may cause interference and oscillation).

4.5 Application Control
4.5.1 Jog Running
In some applications, the AC drive needs to run at low speed temporarily to facilitate equipment
testing. In this case, jog running applies. If jog running is adopted, F6-00 must be set to 0 (direct start)
and F6-10 must be set to 0 (decelerate to stop). The following figure shows the relationship between
the output frequency and acceleration/deceleration time during jog running.
