©NationalInstruments Corporation 13 MID-7604/7602Power Drive
Output Current Settings
The MID-7604/7602 can provide 0.20–1.4 A peak (0.14–1ARMS),
dependingon the peak output current DIP switch settings for each axis.
DIPs witches 1 through 4 control the peak output current. Table 3 shows the
DIP switch settings for all possible peak output current settings.
Ifyou are connecting m ultiple motors to your MID-7604/7602, verify that
the total powerdissipated by the motors at any given time is less than the
totalpower the drive can provide. If the total power requirement exceeds
thecapability of t he driveat any point, the drive will provide less power to
themotors than desired until the total power requirement drops back down.
TheMID-7604/7 602 may overheatunder continuou s operation with loads
thatexceed specified limits.
Caution Afire safety hazard exists when the total power dissipated by the motors exceeds
80 W continuous for a sustained period of time.
