BL Installation and Configuration
2.4. DIP Switch
There is a 10-position DIP switch on the BL 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.

Switches Position Function
Current
Peak Limit
1 Closed Peak is 6% of Ipeak
2 Closed Peak is 13% of Ipeak
3 Closed Peak is 27% of Ipeak
4 Closed Peak is 54% of Ipeak
Switches 1 through 4 affect the GAIN adjustment of the veloc-
ity loop; closing switches 1 through 4 produces maximum gain
adjustment.
Continuous
Current
Peak
5 Closed Icont is 3% of Ipeak
6 Closed Icont is 7% of Ipeak
7 Closed Icont is 14% of Ipeak
8 Closed Icont is 27% of Ipeak
Closing switches 5 through 8 will allow 50% peak continuous
current for two seconds.
Test 9 Closed Closing this position allows the BAL
pot 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 1-4 affect the full-scale current output range of the amplifier when in current (and in velocity) mode.
When all four switches are closed, the peak current range is not limited. Closing each switch effectively lim-
its the output range of the amplifier by a factor associated with that switch. For example closing only SW1-4
(54%) on a BL10 limits the output current to 5.4 A. Therefore, a 10 V input signal would produce a 5.4 A out-
put; similarly, a 5 V input would produce a 2.7 A output (5V / 10V * 5.4A). It should be noted that switches 1-4
have no effect in dual-phase mode.
Switches 5 through 8 determine the level where the continuous output current will produce a fault. This type
of protection is known as an electronic fuse.
Failure to set these switches can result in damage to the amplifier.
