S21260-SRS

S21260-SRS is a Kollmorgen servo drive in the S200 Servo Drives series. It accepts either single-phase or three-phase input power at a nominal input voltage of 240 VAC, allowing installation with either supported supply configuration. The nominal DC bus voltage is 320 VDC for delivering power to the connected motor. A bus undervoltage fault occurs at 150 VDC to indicate that the DC bus has fallen below the drive’s operating threshold. The regeneration voltage is 397 VDC, which is the bus level associated with handling energy returned during motor deceleration.

The drive provides 12 ARMS of continuous output current for sustained motor operation and 30 ARMS of peak output current for short periods of higher torque demand. Its continuous three-phase power rating is 4,000 W, indicating the power available for ongoing three-phase operation. The connected motor must have a minimum inductance of 0.9 mH to maintain suitable current regulation.

The current loop supports a maximum bandwidth of 3 kHz, enabling rapid control of motor current and torque. The velocity loop has a maximum bandwidth of 800 Hz for responsive speed regulation. An RJ-45 network connector provides the physical connection for network communications.
