1.4.2. DIP Switch
There is a 10-position DIP switch on the BA drive that provides four discrete functions.
The switch permits the user to control maximum allowable current to the motor,
continuous output current, velocity or current operational mode, and test mode. Figure 1-
3 shows the location of this switch on the BA drive. Refer to Table 1-2 for the exact
switch functions.
Table 1-2. DIP Switch Functions
Switches Position Function
*1 closed Peak is 6% of Ipeak
*2 closed Peak is 13% of Ipeak
*3 closed Peak is 27% of Ipeak
Current limit Peak
*4 closed Peak is 54% of Ipeak
* These switches affect the GAIN adjustment of the velocity loop. Maximum gain adjustment
when 1 to 4 are closed.
5 closed Icont is 3% of Ipeak
6 closed Icont is 7% of Ipeak
7 closed Icont is 14% of Ipeak
Continuous Current
Peak *
8 closed Icont is 27% of Ipeak
Test 9 closed
Closing this position allows the BALance
potentiometer to manually control motor
velocity or torque without the need of an
input signal depending upon the setting of
switch 10.
Mode 10
Velocity/Current mode - closing this
position enables the current mode.
Switches 1 through 4 set the peak or maximum output current supplied to the load.
Switches 5 through 8 determine the level where the continuous output current the BA amp
protection circuit will produce a fault. This type of protection is known as an electronic
fuse.
For low duty cycle and low acceleration system requirements, set the DIP switches
equally or to next lower switch setting. For high duty cycle and high acceleration system
requirements, set the DIP switches equally or to next higher switch setting.
Closing DIP switches 1 through 4 will allow peak current. Closing switches 5
through 8 will allow 50% peak continuous current for two seconds.
