Data Sheet

10 GDC3xxx Motor Controller Datasheet Version 1.2 December 28, 2018
Battery Backed Clock and Variables
The controller includes a real-time clock/calendar and RAM storage for user variables. Both
the clock and the RAM storage require a battery to continue running and for the stored
data not to be lost while the controller is powered down. The battery is not installed by
Roboteq. Users who wish to use the clock and/or battery backed RAM variables must
install a battery themselves. The battery socket can be reached by removing the 6 screws
that are holding the cover. Lift the cover to reach the board and insert a 3V, 12.5mm coin-
style battery. Use battery type CR1225 or equivalent.
Measured Amps
The controller includes Amps sensors in line with the motor terminals and on the battery
ground terminals. Both Motor Amps and Battery Amps are therefore measured with precision.
Electrical Specifications
Absolute Maximum Values
The values Table 3, below, should never be exceeded, permanent damage to the controller
may result.
