Kollmorgen SERVOSTAR 600 Servo Drive Field Troubleshooting and Maintenance Guide

Common causes and solutions for code names

F01 radiator overheating environment temperature>45 ° C, fan failure, insufficient installation spacing. Check cabinet ventilation, clean fan filter, confirm reserved ≥ 100mm heat dissipation space above and below

F02 bus overvoltage, insufficient braking power, rapid deceleration, external braking resistor not connected or disconnected. Measure the DC bus voltage (normal should be...)< 450V@230V Input< 900V@480V Input). Check the X8 terminal brake resistor wiring and resistance value (33 Ω)

F04 feedback fault encoder cable breakage, shielding damage, connector looseness inspection X1 or X2 terminal. For Hiperface/EnDet, verify 5V power supply. Try replacing the cable

F05 bus undervoltage input phase loss, power supply voltage too low, fuse blown, measure L1/L2/L3 voltage, check external fuses (use 10AT for S606/610, 20AT for S614/620)

F06 motor overheating motor overload, temperature sensor disconnected (PTC), measure motor temperature with hand feel. Check the wiring of the thermistor (via X1 or X2). Reduce load or increase cooling

F11 brake fault: Short circuit or open circuit in the brake coil. Measure the voltage of the motor brake terminal (24V). Check the 4/5 wiring of X9 terminal, with a maximum holding current of 2A

Check the X9 connector for broken or poor contact of the F12 motor power line, and measure the U/V/W phase resistance (which should be balanced). Check the motor side terminals

F16 main power supply phase loss (BTB) input side is missing two or three phases. Check the main contactor and power supply. If single-phase debugging is required, phase loss detection (PMODE) can be performed through parameter shielding

F19 input phase loss (warning can be configured as fault) is missing the same F16. If the parameter is set to "n05" (warning), the machine will not shut down

F25 commutation error encoder initial phase error, or motor phase sequence reversal check feedback parameter (FBTYPE). For SinCos without data channel type, execute "wake&shake" or correctly set MPHASE

F26 limit switch triggers mechanical collision with hardware limit (PSTOP/NSTOP open circuit). Check if X3 terminal 13/14 is at high level (24V). If triggered, manually move out of the limit range and reset

Note: Faults marked with * (F01, F02, F05, F08, F16, F19, F30) can be cleared through the ASCII command CLRFAULT without the need for a complete power outage and restart.

Warning code (nxx) parsing

Warning does not close the output stage, but prompts potential issues:

Code meaning processing

Confirm whether the continuous power of the braking resistor is sufficient when the n02 braking power reaches the preset limit. For S606-620, the continuous power of the internal resistor is only 200W, and frequent braking requires the external connection of a larger power resistor (up to 1.5kW)

N05 input phase loss (warning) check power supply. If it is a temporary phase loss, it can be ignored, but the source needs to be investigated

N10/n11 PSTOP/NSTOP limit activation check limit switch and wiring. Usually a normally closed contact

N14 SinCos commutation incomplete (wake&shake) vertical axis strictly prohibited from using this mode! If necessary, ensure that the motor can shake freely, otherwise use an encoder with a data channel (EnDat/Hiperface) instead

Common on-site troubleshooting table (based on manual summary)

Possible causes and measures for the phenomenon

Motor not turning enable signal not applied (ENABLE=0V) X3/15+24V (high-level enable)

Check the voltage (24V) at terminal 4/5 of X9 if the brake is not released. Brake release requires a delay of approximately 100ms (parameter setting)

Wrong motor phase sequence, swapping any two phases (such as U and V)

Encoder wiring error check X1/X2 pin definition, use Kollmorgen prefabricated cable

Motor oscillation speed loop Kp is too high. Use DRIVE. EXE software to reduce Kp (speed loop proportional gain) and observe the response

If AGND is not connected to the controller ground, X3/1 (AGND) must be short circuited to the analog ground of the upper computer

Replace the damaged shielding layer of the feedback cable and ensure that the shielding layer is grounded through the front plate shielding clip

Driver following error (F03): If Ipeak or Irms is set too low, increase Ipeak (peak current limit), but not exceed the rated value of the motor

The acceleration and deceleration slope is too steep, which prolongs the speed slope time (parameters ACC/DEC)

Motor overheating Ims (effective current) exceeds the rated value of the motor, reducing the load or increasing the motor model; Check the I ² t threshold

Communication failure (RS232) using a straight line instead of a cross line requires the use of a null modem cable (2-3 cross, 5 straight)

COM port occupied by other programs. Close other software and select COM port again

The external resistance value of the brake circuit fails and does not match (must be 33 Ω). The measured resistance at both ends of X8 should be 33 ± 5%

Disconnect the brake resistor fuse and check the external fuse (10 AT for S606/610, 10 AT for S614/620)
