Product Description:

The HMS02.1N-W0028-A-07-NNNN is a drive controller developed by Bosch Rexroth Indramat, a renowned name in motion control technologies and automation solutions. This drive controller is part of the IndraDrive HMS series and is designed to manage single-axis systems. The modular structure of this drive controller enhances its usability in various high-precision applications within industrial automation to provide reliable performance in motor control and drive systems.

The HMS02.1N-W0028-A-07-NNNN delivers a continuous current of 25 A and a maximum current of 28 A to make it suitable for demanding motor applications. The drive controller operates on a DC bus nominal voltage of 700 V that ensures efficient power management. The drive controller supports both synchronous and asynchronous three-phase AC motors that require an output voltage of 0 to 500 V. The rated input voltage for the controller is between 254 and 750 V DC with a rated input current of 18.4 A. The device uses an air-cooling method, utilizing an internal blower that provides forced air ventilation at a rate of 17 to 20 m^3/h to maintain its operational efficiency. The IP 20 protection level ensures adequate safeguarding against dust and other particles.

With measurements of 352 mm x 205 mm x 50 mm and a weight of 3.5 kg, the controller is small and easy to carry. Because HMS02.1N-W0028-A-07-NNNN drive controller can work in temperatures between 0 degrees C and 40 degrees C, it can be used effectively in controlled settings. The installation requires a minimum clearance of 80 mm above and below to facilitate proper airflow and avoid overheating. The drive controller is designed with a switching frequency ranging from 4 to 8 kHz to provide reliable control performance. We provide a one-year replacement warranty and global shipping for our products.

Fault / Error Code	What it Means	Typical Corrective Action
F218	Drive-amplifier heat-sink temperature has exceeded the shut-down limit	Improve cabinet airflow, clean/replace blower, let the unit cool < 45 °C, then clear the fault with Class 1 Reset
F219	Motor thermal sensor signalled an over-temperature event (≈ 155 °C)	Reduce load/duty-cycle, verify motor fan path & thermistor wiring, allow full cool-down before re-enabling
F226	DC-bus under-voltage detected while the drive was enabled	Check mains for brown-outs, be sure Drive Enable drops before DC power disappears; restore supply then reset
F8022	Encoder 1: signals incorrect (wiring / encoder fault)	Inspect & re-seat encoder cable, route away from power lines, replace encoder or interface card if fault repeats
F8025	Over-voltage in the power section (regen energy too high)	Lengthen decel ramps, check braking resistor sizing/connection, clear when DC-bus ≤ 730 V
F8028	Over-current in the power section	Inspect motor cable for shorts, verify current limits & motor data, test IGBT stage if fault persists
F8060	Over-current in power section (fast hardware trip)	Same actions as F8028; additionally check for phase-to-phase shorts and replace damaged devices
F8070	+24 V control-supply under-voltage	Measure 24 V rail at X31, tighten terminals, up-size PSU if sagging under load, then reset the fault
F8091	Power section defective (internal hardware monitoring trip)	Run IndraDrive Diag self-test; if fault re-occurs replace inverter power stage or send for repair
F4001	“Double MST” — two consecutive missing SERCOS master sync telegrams	Check fibre-optic ring, clean/replace damaged leads, match SERCOS cycle times, then restart the network
