9.7 parameter details
A08888 Starting Mode
There are 3 starting mode. User can set this parameter by keyboard referring to
chapter 8-1 and chapter 9.
A18888 Initial Voltage
This parameter is valid at the Voltage Ramp mode. If the Voltage Ramp mode is
selected, the lamp V at the keyboard are light.
This parameter indicates that the initial output voltage of the product at the
instant of starting and also indicates the initial voltage of the motor (see figure
6-1).The more this parameter is, the more the starting torque is. The default value
is 30. For the fan pump load, this parameter should not set bigger. For the load
which has bigger static resistance, this parameter can be increased. This parameter
can be adjusted between 20-50%. If the Current Limit mode is selected, this parameter
is invalid.
A28888
Jogging
Voltage
At this mode, the parameter range is 5-75%. When this parameter is set the lamp V
at the keyboard are light.
At Jogging mode, the output voltage of this product maintains unchanged(it is the
set parameter). If this parameter is too low, the motor may don’t turn. It’s normal.
User can set this parameter by keyboard referring to chapter 8-1 and chapter 9.4.
A38888 Ramp Time
This parameter indicates that the maximum time between the beginning of the
starting to the end of the starting. The default is 30s.。
If the starting current is not less the 125% of rate current after the time is reached,
the soft starter enter the protection state 3s later automatic.
This parameter is set according to the load type. For the heavy load and big
inertia load type, this value can be increased. For light load type, the starting
time may be shorter then the time user set. It is normal if the starting process
is all right. This parameter is invalid at the Current Limit mode.
A48888
Starting Current Limit
At the Current Limit mode, this parameter indicate the maximum current limit during
starting. The range of this parameter is 20%~400% of Ie. The default is 300, it means
the starting current is the triple of the rate current. When this parameter is set,
lame A on the keyboard is light,
For the fun and pump load type, it is all right. For other load type, user can
modify it according to the character of load type. It is better to set between 250%
and 350%. This parameter is invalid at the Voltage Ramp mode.
