186 Actual signals and parameters2112 ZERO SPEEDDELAY Defines the delay for the Zero Speed Delay function. Thefunction is useful in applications where a smooth and quickrestarting is essential. During the delay the drive knowsaccurately the rotor position.No Zero Speed DelayThe drive receives a stop command and decelerates alonga ramp. When the motor actual speed falls below an internallimit (called Zero Speed), the speed controller is switchedoff. The inverter modulation is stopped and the motor coaststo standstill.With Zero Speed DelayThe drive receives a stop command and decelerates alonga ramp. When the actual motor speed falls below an internallimit (called Zero Speed), the zero speed delay functionactivates. During the delay the functions keeps the speedcontroller live: The inverter modulates, motor is magnetizedand the drive is ready for a quick restart.0.0 s0.0…60.0 s Delay time. If parameter value is set to zero, zero speeddelay function is disabled.1 = 0.1 s2113 START DELAY Defines the start delay. After the conditions for start havebeen fulfilled, the drive waits until the delay has elapsed andthen starts the motor. Start delay can be used with all startmethods. If start delay is zero, the delay is disabled. Duringthe start delay, alarm START DELAY is shown.0.00 s0.0…60.0 s Delay time 1 = 0.01 s22 ACCEL/DECEL Acceleration and deceleration times2201 ACC/DEC 1/2SELDefines the source from which the drive reads the signalthat selects between the two ramp pairs,acceleration/deceleration pair 1 and 2.Ramp pair 1 is defined by parameters 2202…2204.Ramp pair 2 is defined by parameters 2205…2207.DI5NOT SEL Ramp pair 1 is used. 0DI1 Digital input DI1. 1 = ramp pair 2, 0 = ramp pair 1. 1DI2 See selection DI1. 2DI3 See selection DI1. 3DI4 See selection DI1. 4DI5 See selection DI1. 5All parametersNo. Name/Value Description Def/FbEqt tSpeed controllerswitched off: Motorcoasts to stop.Speed controllerremains live.
