Acceleration and deceleration
Start-time hold function (Pr. 571)
This function holds the time set in Pr. 571 and the output frequency set in Pr. 13 "Starting fre-
quency".
This function performs initial excitation to smooth the motor drive at a 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.
