15F5M1E-35GA KEB COMBIVERT F5 Servo Drive Inverter 11kW

Product Overview

The 15F5M1E-35GA is a high-performance closed-loop drive controller from the KEB COMBIVERT F5 series.

This universal servo drive provides precise velocity, torque, and position control for synchronous and asynchronous AC motors.

It processes dynamic motor feedback including Resolvers, Incremental Encoders, Sin/Cos, Absolute Encoders, Hiperface, and EnDat systems.

Industrial engineers integrate this drive into complex automated machinery to offload motion tasks from host PLCs.

Installation & Setup Recommendations

• Mount the unit vertically on a smooth, flat backplate to maintain uninhibited vertical airflow.
• Maintain a minimum clearance of 100 mm above and below the drive housing for convective heat dissipation.
• Connect motor leads using shielded power cables and bond shields directly to the drive ground clamp.
• Wire control signals separately from three-phase AC input lines to prevent electromagnetic interference.

Global PLC Spare HUB's Insight

The 15F5M1E-35GA remains a workhorse drive across automated bottling lines.

Field experience indicates that encoder feedback card seated improperly causes sporadic velocity feedback trips.

During a line overhaul, our engineers resolved intermittent overcurrent alarms by resetting the internal encoder plug interface.

Verifying motor PTC sensor resistance directly at the control terminal block prevents unnecessary thermal shutdown faults.

Selection & Purchasing Guidance

• Verify that your motor nominal current does not exceed the drive output rating of 24 A continuous.
• Confirm the required feedback option card (Resolver, Incremental, EnDat) matches your motor transducer hardware.
• Check if external braking resistors are required for high-inertia deceleration cycles.
• Ensure line reactor filtering is present on power lines with unstable ambient AC supply voltage.

Frequently Asked Questions

What distinguishes the COMBIVERT F5 MULTI drive series from BASIC and COMPACT models?

The MULTI series incorporates closed-loop field-oriented control cards supporting feedback options like Resolvers and EnDat encoders.

Can this drive operate directly off a DC bus supply instead of three-phase AC mains?

Yes, the intermediate DC circuit accepts 420-720 VDC directly across the positive and negative bus connections.

How do technicians reset drive parameter sets back to factory default values?

Access parameter CP.28 using the pluggable keypad module and set the value to restore factory defaults.

Which parameter controls maximum switching frequency to minimize audible motor noise?

Adjust parameter uF.00 up to 16 kHz to reduce motor hum, taking drive derating factors into consideration.

What safety pre-check prevents internal dynamic braking chopper circuit damage?

Measure dynamic braking resistor resistance to ensure it meets minimum ohm ratings before applying power.
