Eurocard Mount
All connections to the amplifier are made via the DIN connector.
The Eurocard may be ordered with the same additional options as the MB4 card:
Voltage-Mode operation with IR compensation (-V option)
PWM Inputs (-D option)
Edge Filters (-F option)
Heatsink options available with the Eurocard mounting are the -H, and -HX, for standard
and extended heatsink. The 10HP spacing will accept the -H heatsink, but a wider
spacing is required for the -HX extended heatsink.

Note that the power ground, pos/neg outputs, and high voltage signals each share four
pins. These pins should be wired together on the backplane so that the higher currents
carried by these these signals are shared by the pins.
Jumper Settings
1. Basic: Standard voltage to current configuration
2. Voltage Mode: Voltage-in to voltage-out mode.
3. IR Comp Voltage mode with armature resistance compensation
4. PWM 0-100%: PWM signal applied to REF+ input, Direction signal applied to REF- input.
5. PWM 50%: PWM signal applied to REF- input, 50% duty cycle gives 0 output, 0 and 100%
duty cycle give max positive/negative outputs.
