8 STP MIN SP = N
G7.7 / Minimum
stop speed
N
Y
N
Allows user to stop the motor when the speed is below the SD700
lower speed limit.
OPT FUNCTION
N=NO
In this case, the motor will continue to operate at
minimum speed defined as minimum speed limit
(set in G10.1 or G10.3), even if the speed
reference is below these settings. For example, if
‘1 MIN1 SP=+30.00%’, and the speed reference
is +20.00%, the equipment will operate at
+30.00%, and never below this value.
Y=YES
In this case, the drive will automatically start when
the speed reference is above the value set as
minimum speed limit. While the speed reference
is below this value, equipment will be in 'READY'
status.
If the drive is decelerating and the reference is
below the minimum speed value, then the
equipment will stop by spin.
Note: If you want to stop the motor when the reference is below a
fixed speed set point, you should set this parameter to YES.
Additionally, you should set the correct values in 'G10.1 MIN1 SP' or
'G10.3 MIN2 SP'.
YES
9 OFFdly = OFF
DELAY AFTER STOP
G7.8 / Delay time
between stop
and next start
OFF=0.000
to 10.0s
OFF
Allows setting a delay time between the moment the drive has
stopped and the next starting. The next time the drive has to start it
will consider no additional delay time unless parameter ‘G7.5
START DLY’ had been set to a value different from OFF.
YES
10 RUN AFTR VFL = Y
G7.10 / Run after
occurring power
loss
N
Y
Y
Allows setting of the drive to start automatically when a main power
supply loss occurs and it is recovered again (power supply loss or
instant power supply loss).
OPT FUNCTION
N=NO
The drive will not start after power supply
recovery occurs even the start command is
active. User should deactivate this signal and
activate it again.
Y=YES
The drive starts automatically when power supply
is recovered after power supply loss occurs and if
the start signal is active.
Note: If start / stop control is done by keypad, the drive will not start
automatically after power supply loss occurs and it is recovered
again.
YES
11 SPNstr B = OFF
SPIN START TUNE
G7.11 / Accuracy
setting for
Starting by Spin
OFF=0,
1 – 100%
OFF
It allows setting the accuracy of the speed searching function when
the drive starts by SPIN mode. Usually, the optimum value is
between 2 and 5%. As the value is lower, more accuracy is
required.
YES
