IQ 2000/5000 Installation Manual
PDMs are manufactured in different packages which cover a wide range of power capability.
The IQ-2000 Series PDMs incorporate an integral power supply in each PDM, and supply con-
tinuous torques of 3 to 450 inch–pounds in combination with standard motors. The IQ-5000
Series PDMs use a separate power supply module, which can be shared among multiple PDMs,
and provide continuous torques of 20 to 750 inch pounds with the standard motors.
IQ-2000 PDMs
The PDM-10, PDM-20, PDM-30, PDM-75, and PDM-150B are rated for 10, 20, 30, 75, and 150
amp peak currents respectively. These modules are packaged with an integral power supply to
achieve a small size.
Input power to a PDM-10, PDM-20, or PDM-30 is single phase 115 or 230 VAC. Input power to
a PDM-75 or PDM-150B is three-phase 115 or 230 VAC. The input power may be optionally
isolated through a transformer. These PDMs have a built-in solid state “soft charge” of the
internal DC bus capacitor. They also include a built-in dissipative shunt regulator that provides
synchronous motor dynamic braking. The PDMs allow use of an optional external shunt resistor
for applications requiring higher shunt power capability than provided by the internal shunt
resistor.
