MOTOROLA MVME5110-2261 Digital I/O card

The drive is capable of direct-line operation. All units are fully- isolated and do not require external isolation transformers. Inrush current on the connection to the line is internally-limited to a safe level for the drive. There are no voltage selection or ranging switches required to operate within the specified voltage input ranges. It is your responsibility to supply appropriate fuses or circuit breakers in the TB1 AC Power motor power lines to comply with local electrical codes. The control input power required should be between 15 and 25 watts. The AC input motor power depends on output power and the losses in the power stage. The control power input has a single UL/CSA rated fuse in line with one of the AC line inputs.

Diagnostics and Protection Circuits 

The drive is fully protected against “normal” abuse and has two LEDs on the front panel to indicate drive status. The servo drive has the following specific protections: z Output motor short circuit protection line-to-line and line-to-neutral. z Interface to Danaher Motion's Pacific Scientific standard motor PTC or a normally closed thermostat to sense motor over temperature. z Internal monitoring of the power stage heat sink temperature for drive over temperature. z Bus over voltage detection. z Bus under voltage fault with adjustable threshold.
