KOLLMORGEN P70360 High Performance Microstep Driver

（1） Common faults and solutions

Possible causes and solutions for the fault phenomenon

Motor direction error, motor phase wire reversed; Wrong polarity setting for rotation, switching motor A ± or B ± wiring; Change 'Rotation Polarity' through P7000Tools

Drive overheating (red light flashing 4 times), ambient temperature exceeding 40 ° C; poor heat dissipation; Excessive load duty cycle increases fan cooling; Clean the heat sink; Reduce the frequency or load of exercise

Blocked rotor fault (red light flashing once), high motion acceleration/speed; Load inertia exceeding the range reduces Profile acceleration/velocity; Optimize the load inertia ratio setting; Check for mechanical jamming

Overcurrent fault (red light flashing twice), motor winding short circuit; Cable damage; Measure the resistance of the motor winding when the output current exceeds the limit (normally there should be no short circuit); Replace the cable; Reduce motor current (adjusted through software)

Overvoltage fault (red light flashes 3 times) Input voltage is too high; Excessive regenerative energy check AC input voltage (≤ 240 VAC); Increase regenerative resistance; Reduce deceleration rate

Profile cannot execute driver as SDN version (without indexing function); Move Select input configuration error confirmed model as PNN/R4N; Check if the Move Select input is continuous (starting from DIN1); Configure the 'Start Move' input

（2） Safety regulations

Electrical safety

The driver contains high-voltage components (with a maximum DC bus voltage of 440 VDC). After power failure, it is necessary to wait for 2 minutes before touching the wiring terminals. Before operation, measure the bus voltage to be less than 40 V.

The PE wire needs to be reliably grounded (cross-section>10 mm ² or double PE wiring), and the motor casing should be grounded through J6-5 to avoid capacitor coupling causing the casing to become electrified.

It is prohibited to rely on the "Enable" input as an emergency stop. An additional hard wired emergency stop circuit needs to be configured to cut off the power supply to the driver motor (J6).

Mechanical safety

The surface temperature of the motor during operation may exceed 70 ° C, and direct touch is prohibited; Vertical axis applications require additional mechanical braking (the driver brake is only used for parking and frequent braking is prohibited).

Ensure that there are no personnel/obstacles within the range of motion of the motor during debugging. Use low-speed Jog test for the first operation to confirm that there is no jamming or abnormal vibration.

EMC Compliance

An external power filter (such as Corcom 6EQ1) is required, installed at the power inlet, with a filter input/output cable spacing of ≥ 100mm to avoid cross interference.

Shielded twisted pair cables are used for motor and control cables, and the shielding layer is grounded 360 ° (through metal clamps). When the cable length exceeds 15m, a magnetic ring (such as Fair rite 0444167281) needs to be added at the motor end.
