Stop function
Two stop functions can be selected in this
application:
0 = Coasting
The motor coasts to a halt without control
from the frequency converter after the
Stop command.
1 = Ramping
After the Stop command, the speed of the
motor is decelerated according to the set
deceleration parameters.
If the regenerated energy is high it may be
necessary to use an external braking
resistor for to be able to decelerate the
motor in acceptable time.
I / O start stop logic
Values 0...4 offer possibilities to control the
starting and stopping of the AC drive with digital
signal connected to digital inputs. CS = Control
signal.
The selections including the text 'edge' shall be
used to exclude the possibility of an unintentional
start when, for example, power is connected, re-
connected after a power failure, after a fault reset,
after the drive is stopped by Run Enable (Run
Enable = False) or when the control place is
changed to I / O control. The Start / Stop contact
must be opened before the motor can be started.
I/O stop logic uses accurate stop mode.Accurate
stop mode is that the stop time is fixed from
falling edge of DI to power stopping the drive.
