ZERO SPEED DELAY Defines the delay for the Zero Speed Delay function. The function is useful in
applications where a smooth and quick restarting is essential. During the
delay the drive knows accurately the rotor position.
Zero speed delay can be used e.g. with jogging function or mechanical
brake.
No Zero Speed Delay
The drive receives a stop command and decelerates along a ramp. When the
motor actual speed falls below an internal limit (called Zero Speed), the
speed controller is switched off. The inverter modulation is stopped and the
motor coasts to standstill.
With Zero Speed Delay
The drive receives a stop command and decelerates along a ramp. When the
actual motor speed falls below an internal limit (called Zero Speed), the zero
speed delay function activates. During the delay the functions keeps the
speed controller live: The inverter modulates, motor is magnetised and the
drive is ready for a quick restart.
0
0.0…60.0 s
Delay time. If parameter value is set to zero, zero speed delay function is
disabled.
1 = 0.1 s
22 ACCEL/DECEL
Acceleration and deceleration times
2201
ACC/DEC 1/2 SEL
Defines the source from which the drive reads the signal that selects
between the two ramp pairs, acceleration/deceleration pair 1 and 2.
Ramp pair 1 is defined by parameters
Ramp pair 2 is defined by parameters
DI5
NOT SEL
Ramp pair 1 is used.
0
DI1
Digital input DI1. 1 = ramp pair 2, 0 = ramp pair 1.

COMM
Fieldbus interface as the source for ramp pair 1/2 selection, i.e. control word
FB CMD WORD 1 bit 10. The control word is sent by the fieldbus
controller via the fieldbus adapter or embedded fieldbus (modbus) to the
drive. For the control word bits, see section
on
page

This setting applies only for the DCU profile!
