Figure 15 Current Limit Jumper Configuration
Low Current Setting (JP1)
The LC jumper and associated “LC” command have three possible configurations for both the
SDM-20240 and SDM-20242:
LC command set to 1 and LC jumper ON – causes motor to use 25% (50% rev A & B) of
peak current while at a “resting” state (profiler is not commanding motion). This is the
recommended configuration to minimize heat generation and power consumption.
LC command set to 1 and LC jumper OFF – turns amplifiers off when at “rest” (not
commanding motion).
LC jumper ON or OFF and LC command set to 0 (default). Full current to drive even
when at rest. Proper heat dissipation is critical if using LC0.
The LC command must be entered after MT-2,-2,-2,-2. LC should be set for each axis – so
LC1,1,1,1 will cause all axes to operate in “Low Current” mode.
Low Current Setting SDM-20240/20242: LC n,n,n,n,n,n,n,n
n = 0
100%
n = 1
25% * / 0%
* LC function for SDM 20240 requires jumper
installation at JP1, else 0% current occurs.
SDM-20240 Half Step jumper (JP1) – determines whether pulses from the
controller are interpreted by the Driver chips as whole or half step increments.
Half Step Jumper On = Half step
Half Step Jumper Off = Full step
