Product Instructions & Technical Notes

When installing the Indur Indureg FU-1.5, ensure the drive is mounted vertically to allow for optimal airflow through the heatsink. It is critical to use shielded motor cables to minimize electromagnetic interference (EMI) with nearby sensitive electronics. Before commissioning, verify the motor’s nameplate data (Voltage, Current, RPM) and input them into the drive’s parameter set to ensure proper thermal protection. If the drive has been in storage for over a year, it is recommended to “reform” the internal capacitors by applying power gradually before running a motor at full load.

Q&A – Frequently Asked Questions

Q1: Can this drive be used for a 2.2kW motor? A: No, the FU-1.5 is rated specifically for 1.5kW. Using a larger motor may lead to constant overcurrent tripping or internal damage to the drive’s IGBT modules.

Q2: Does this unit support regenerative braking? A: Most FU-1.5 units support external braking resistors to dissipate energy during rapid deceleration, though the resistor must be sized according to the drive’s technical manual.

Q3: Is it possible to control the drive via a PLC? A: Yes, the AL-3402 typically includes digital inputs for Start/Stop and an analog input (0-10V or 4-20mA) for frequency (speed) reference from a PLC.

Q4: What should I do if the drive displays a fault code? A: Refer to the Indureg manual’s “Error Codes” section. Common faults like “OC” (Overcurrent) or “OV” (Overvoltage) usually indicate issues with the motor load or rapid deceleration ramps.
