START INTRL FUNC
Defines how the Start Interlock input on the RMIO board affects the drive
operation.
Note:
In the Master/Follower mode, the settings must be the same in both the
Master and the Follower drives.
OFF2 STOP
Drive running: 1 = Normal operation. 0 = Stop by coasting.
Drive stopped: 1 = Start allowed. 0 = No start allowed.
Restart after OFF2 STOP: Input is back to 1 and the drive receives rising edge
of the Start signal.
1
OFF3 STOP
Drive running: 1 = Normal operation. 0 = Stop by ramp. The ramp time is
defined with parameter 22.07 EM STOP RAMP.
Drive stopped: 1 = Normal start. 0 = No start allowed.
Restart after OFF3 STOP: Start Interlock input = 1 and the drive receives rising
edge of the Start signal.

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.
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.
