Actual signals and parameters8321.10 ZERO SPEED DELAY Defines the delay for zero speed delay function. The function is usefulin applications where a smooth and quick restarting is essential.During the delay the drive knows accurately the rotor position.No Zero Speed DelayThe drive receives a stop command and decelerates along a ramp.When the motor actual speed falls below an internal limit (called ZeroSpeed), the speed controller is switched off. The inverter modulation isstopped and the motor coasts to a standstill.With Zero Speed DelayThe drive receives a stop command and decelerates along a ramp.When the actual motor speed falls below an internal limit (called ZeroSpeed), the zero speed function activates. During the delay thefunctions keeps the speed controller live: the inverter modulates,motor is magnetized, and the drive is ready for a quick start.0.0…60.0 s Delay Time 10 = 1 s21.11 E-STOP COAST DLY Time allowed for the drive to stop after an e-stop command is receivedbefore an internal coast stop is commanded.0…100 s Setting range. 10 = 1 s22 ACCEL/DECEL Acceleration and deceleration times.
