About the 1398-DDM-075

The Allen-Bradley 1398-DDM-075 is an Ultra 200 servo drive. This drive was one of Allen-Bradley's early servo drive products. It is a microprocessor-based servo drive with built-in functions for managing drive current, speed, and position.Ultra 200 servo drives (such as the 1398-DDM-075) are compatible with brushless servo motors.

Specifically, the 1398-DDM-075 has an AC input voltage requirement of 100-240VAC rms, single-phase or three-phase, and an input frequency of 47-63 Hz. It also has an auxiliary input that is isolated from the supply voltage of the main AC input circuit. The auxiliary AC input is rated at 100-240 VAC, single phase, 47-63 Hz, and has an input current of 1.0 amp for 100 VAC and 0.5 amp for 240 VAC.

The drive has a peak output current of 50 amps for single-phase input and 75 amps for three-phase input, and a continuous output current of 15 amps for single-phase operation and 35 amps for three-phase operation. Peak output power is 14 kilowatts for single phase, 20 kilowatts for three-phase peak output, and 7.5 kilowatts for three-phase continuous output.

The drive has a total line voltage of 141-339 VDC, bus capacitance energy absorption of 152 Joules, and bus capacitance of 4290 µF. power dissipation is 300 watts.

The 1398-DDM-075 has five (5) user-configurable 24 Volt, current-absorbing, opto-isolated, active-high inputs; one (1) fixed assignment control (ENABLE), current-absorbing, opto-isolated, active-high input; four (4) assignable 24 Volt, current-absorbing, opto-isolated, active-high outputs; and two (2) dedicated (Brake and Drive Ready), normally open relay outputs. relay outputs. The embedded analogue input/output channels include two dedicated 10-bit 0 - 10 volt analogue inputs (+I LIMIT and -I LIMIT) and two selectable ±10 volt analogue outputs, one 12-bit and one 8-bit (ANALOG1 and ANALOG2).

The 1398-DDM-075 module also has analogue outputs with 8-bit and 12-bit resolution. The analogue input voltage range is 0-10 volts. The analogue inputs have 10-bit resolution. 1398-DDM-075 has an integrated power supply and a shunt regulator, which uses a microcontroller to manage the machine's position, speed, and current. 1398-DDM-075 servo drives are powerful and require minimal maintenance. When maintenance is required, the standard procedure is to check that cable insulation and connections are intact. Recommended humidity limits are between 5% and 95%, the same as other ULTRA 200 drives. 1398-DDM-075 weighs 21.32 lbs. Peak output currents are 50A for single-phase power supplies and 75A for three-phase power supplies. the input frequency is 47-63 Hz. when operating the 1398-DDM-075 ULTRA 200 Servo Drive from a single-phase power supply, the current limit must be set correctly to avoid damage to the module. the 1398-DDM-075 can be operated from a single-phase power supply. the 1398-DDM-075 can be operated from a single-phase power supply.
