The first 6 switches of dip switch 2 are the current settings and are approximately 40 ma per bit for 2.5 amp 
drivers and 56ma per bits for a 3.5amp driver. The off position of the switch selects the current; switch 6 is 
the most significant bit. The PMC supplied motors run at approximately 2.5 amp/phase peak current. The 
motor current table above is for 2.5 amp version. In the 2.5amp version the user can activate the standby 
mode by selecting switch 2-8 to off position. Standby mode is automatically entered in the 3.5 amp model 
regardless of the switch setting 

Test 

 
 

This is a mode that is entered upon power up if switch 2-7 is in the on position. The motor will rotate 

at 0.7 rev/sec after power up. Power must be turned off and switch 2-7 put in the off position to leave test 
mode.  
The commands are ignored in test mode. Set Test mode to the off position before entering command mode

.

 

 

Auto-Standby 

 

 

The motor current is reduced to 50% after 2 seconds of no movement in the 2.5 amp version when 

switch 2-8 is selected OFF position. The motor current goes to standby mode regardless of the switch 
setting in the 3.5 amp version.
