DESCRIPTION OF PROGRAMMING PARAMETERS
Parameter /
Default Value
G7.8 / Minimum
stop speed
Allows user to stop the motor when the speed is below the SD700 lower speed
limit.
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.
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
setpoint, you should set this parameter to YES. Additionally, you should set the
correct values in 'G10.1 MIN1 SP' or 'G10.3 MIN2 SP'.
9 OFFdly = OFF
DELAY AFTER STOP
G7.9 / Delay time
between stop
and next start
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 ‘G7.6 START DLY’ had been set to a value different
from OFF.
G7.10 K/ Run
after occurring
power loss
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).
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.
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.
11 SPNstr B = OFF
SPIN START TUNE
G7.11 / Accuracy
setting for
Starting by Spin
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.
12 OFFdly2=OFF
DELAY AFTER STP2
G7.12 / Delay
time for start
command after
stop
Delay time for start command after producing a stop. If the start command is given
after the time set in this parameter has elapsed, the drive will start immediately.
G7.13 / Start
after fault reset
with start
command
It allows starting the drive after resetting the fault produced in the equipment,
whenever the start command is activated.
After resetting the fault, the drive will not start
although the start command is activated. To start,
the user should deactivate the start command
and activate it again. This operation mode
guarantees a starting controlled by an operator
although the fault is reset. This option is
commonly used in remote controls in order to
increase the safety at the starting.
The drive will start after resetting the fault,
whenever the start command is activated.
Sets the time period during which the drive maintains the magnetic flux in the
motor after reaching zero speed when stopping.
G7.15 /
Magnetization
Time
Sets the period of time during which the motor is being magnetized before the
start.
G7.16 /DLY Start
after Run.
Operates with G7.13. Estimates the minimum time that the start order has to be
disabled before starting after the reset..
