© National Instruments Corporation 13 MID-7604/7602 Power Drive
Output Current Settings
The MID-7604/7602 can provide 0.20–1.4 A peak (0.14–1ARMS),
depending on the peak output current DIP switch settings for each axis.
DIP switches 1 through 4 control the peak output current. Table 3 shows the
DIP switch settings for all possible peak output current settings.
If you are connecting multiple motors to your MID-7604/7602, verify that
the total power dissipated by the motors at any given time is less than the
total power the drive can provide. If the total power requirement exceeds
the capability of the drive at any point, the drive will provide less power to
the motors than desired until the total power requirement drops back down.
The MID-7604/7602 may overheat under continuous operation with loads
that exceed specified limits.
Caution
A fire safety hazard exists when the total power dissipated by the motors exceeds
80 W continuous for a sustained period of time.
