Product Description:

S60301-NA is a SERVOSTAR 603 with AS option variant from Kollmorgen. This designation confirms the drive’s enhanced safety features that prevent unintended restarts. It can support a rated installed load of 2 kVA and operates at a rated supply voltage of 3 x 230V (50Hz) or 3 x 208V (60Hz) up to 480V (±10%). The rated DC bus link voltage is 290 V to 675 V DC, with a broad voltage window that allows for flexible power distribution for various system configurations. The unit delivers a rated output current of 3 A (rms, ±3%).

Additionally, the module can supply a peak output current of 6 A for roughly 5 seconds. This capability meets transient load demands during startup surges. The output stage clock frequency is 8 kHz, increasing to 16 kHz when VDCmax equals 400V. The overvoltage protection threshold spans from 450 V to 900 V. This safeguard protects internal components against voltage spikes. Motors with larger inductive loads may be supported by the maximum load inductance of 75 mH, while the lowest load inductance is 12 mH. With smaller loads, stability is maintained at this lower limit. Because of its IP20 rating, the S60301-NA's enclosure protection is appropriate for indoor industrial applications.

Protection against dust and other minor environmental conditions is guaranteed by this certification. At rated data, the ambient operating temperature falls between 0C and +45C, with power derating above +45C. Quiescent dissipation is approximately 15 W when the output stage is disabled. This low power loss reduces energy consumption during idle periods. Dissipation at rated current is about 40 W, including power supply losses but excluding brake dissipation. This thermal efficiency supports sustained operation under load. The drive offers 2 analog setpoint inputs (±10V, 14bit/12bit resolution), 4 programmable digital inputs, and 2 programmable digital outputs. This versatile I/O configuration enables precise and flexible control integration.

Fault / LED code What it means on the drive display First corrective actions
F01 – Heat-sink over-temperature Heatsink ≥ ≈ 80 °C, power stage is shut down

• Lower ambient/cabinet temp

• Clean or blow-out vents & fan

• Verify fan cartridge is running

• Restore factory MAXTEMPH = 80 °C if it was lowered 

F02 – DC-bus over-voltage Regeneration or high mains pushed the DC link above limit

• Check/size braking resistor & fuse

• Link DC buses of multiple drives

• Lengthen decel ramps

• Verify correct mains setting in Basic Setup 

F06 – Motor over-temperature PTC/thermostat inside motor opened or sensor defect

• Improve motor airflow

• Measure/replace sensor

• Reduce load or duty cycle

• Adjust MAXTEMPM only after confirming sensor type 

F12 – Motor phase missing One motor phase open or shield issue

• Inspect motor connector seating

• Check phase wiring & shields

• Add motor choke / shorten long leads if cable capacitance is high 

F13 – Internal amplifier temperature Internal logic area too hot

• Enhance cabinet cooling

• Separate heat-emitting gear

• Check TEMPE threshold

• Service drive if fault pairs with F17 

F14 – Output-stage fault Short or device fault in IGBT bridge

• Meg-ohm test motor & cable

• Replace damaged cable

• If insulation OK, return drive for repair 

F16 – Supply BTB/RTO One or more mains phases missing while ENABLE is high

• Verify 3-phase feed & fuses

• Respect power-on → ENABLE sequence

For single-phase/DC feeds change BTB settings 

F17 – A/D-converter error Internal measurement chain upset (often EMC)

• Inspect grounding & cable shields

• Route motor/power cables away from feedback

• If persistent, service the drive 

F18 – Regen-circuit fault Braking transistor or wiring error

• Check internal vs external resistor jumpers

• Replace blown regen-fuse

• Test transistor; service if shorted 

F23 – CAN-bus OFF Severe CANopen communication fault

• Inspect bus cable & 120 Ω terminators

• Check baud-rate, node-ID clashes

• Keep CAN shield bonded at both ends
