Parameter
Start-time hold function (Pr. 571)
This function holds the time set in Pr. 571 and the output frequency set in Pr. 13 "Starting
frequency".
This function performs initial excitation to smooth the motor drive at a start.
Fig. 6-29: Holding time at start
NOTES
When the start signal was turned off during start-time hold, deceleration is started at that
point.
At switching between forward rotation and reverse rotation, the starting frequency is valid but
the start-time hold function is invalid.
When Pr. 13 = 0Hz, the starting frequency is held at 0.01Hz.
