Starting Mode Starting Mode
There are 3 Starting mode. User can set this parameter by keyboard referring to There are 3 Starting mode. User can set this parameter by keyboard referring to
chapter 8-1 and chapter 9. chapter 8-1 and chapter 9.
Initial Voltage Initial Voltage
This parameter is valid at the Voltage Ramp mode. If the Voltage Ramp mode is This parameter is valid at the Voltage Ramp mode. If the Voltage Ramp mode is
selected, the lamp V and lamp % at the keyboard are light. selected, the lamp V and lamp % at the keyboard are light.
This parameter indicates that the initial output voltage of the product at 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 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. (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 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 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 can be increased.This parameter can be adjusted between 20-50%. If the
Current Limit mode is selected, this parameter is invalid. Current Limit mode is selected, this parameter is invalid.
Jogging Voltage Jogging Voltage
At this mode, the parameter range is 5-75%. When this parameter is set At this mode, the parameter range is 5-75%. When this parameter is set
the lamp V and lamp % at the keyboard are light. the lamp V and lamp % at the keyboard are light.
At Jogging mode, the output voltage of this product maintains At Jogging mode, the output voltage of this product maintains
unchanged(it is the set parameter). If this parameter is too low, the motor unchanged(it is the set parameter). If this parameter is too low, the motor
may don't turn. It's normal. may don't turn. It's normal.
User can set this parameter by keyboard referring to Tatble 8-1 and User can set this parameter by keyboard referring to Tatble 8-1 and
Chapter 9.4. Chapter 9.4.
Ramp Time Ramp Time
This parameter indicates that the maximum time from the beginning to This parameter indicates that the maximum time from the beginning to
the end of the starting. The default is 30s. When setting this parameter, the end of the starting. The default is 30s. When setting this parameter,
lamp S on the keyboard is light. lamp S on the keyboard is light.
If the starting current is not less the 125% of rate current after the time is If the starting current is not less the 125% of rate current after the time is

This parameter is set according to the load type. For the heavy load type This parameter is set according to the load type. For the heavy load type
and big inertia load type, this value can be increased. For light load type, and big inertia load type, this value can be increased. For light load type,
the starting time may be shorter than the time user set. It is normal if the the starting time may be shorter than the time user set. It is normal if the
starting process is all right. This parameter is invalid at the Current Limit starting process is all right. This parameter is invalid at the Current Limit
mode. mode.
