The 1600i and 3200i have identical functionality, however the 1600i is designed for operation
Line-to-Neutral (240 V nominal) and the 3200i for operation Line-to-Line (415 V nominal).
• All models are of open chassis construction for use in a suitable enclosure.
• The drives have isolated control electronics.
• Closed loop control of both armature current and feedback voltage for precise control of
motor torque and speed.
• Motor and drive are protected by a stall timer to automatically remove power after 30
seconds if the required speed cannot be achieved.
• Up to 150% of the preset maximum current for up to 30 seconds allowing for high, short-
term torques during acceleration etc.
• Independent control of either the current or speed loops by external inputs allow for
torque or speed control applications with overspeed or overcurrent protection.
• Demand signal can be derived from a potentiometer, 0-10 V signal or 4-20 mA loop.
• Speed feed back signal selection: ARMATURE VOLTAGE, or shaft-mounted TACHOMETER.
