1.4.2. DIP Switch
There is a 6-position DIP switch on the BAL drive that provides three discrete functions.
The switch permits the user to control maximum allowable current to the motor (self
commutating modes only), velocity or current operational mode, and test mode. Figure 1-
3 shows the location of this switch on the BAL 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
(self commutating
modes only)
4 closed Peak is 54% of Ipeak
Test 5 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 6
Velocity/Current mode - closing this
position enables the current mode.
The following examples should be used as a guideline for setting the DIP switches.
Example for a BAL20 - Setting Continuous Current Limits
To set the continuous current limit to 5.5A:
5.5A Continuous RMS x 1.414 = 7.8A continuous peak
(7.8A continuous peak/20A max peak) x 100 = 39%.
Open switches 1 and 4; close switches 2 and 3.
