Error / Symptom	Likely Cause	Recommended Fix
Output-overcurrent fault – drive “Enabled” output drops as soon as power is applied	Line-to-line or line-to-neutral short on the motor phases	Isolate and meg-ohm-test motor and cable; repair or replace damaged wiring, then power-cycle the drive.
Bus over-voltage fault – drive disables when DC bus > 75 V DC	Regeneration or incorrect transformer/PSU sizing pushes bus above 75 V	Add dynamic-brake (regen) clamp or larger bulk capacitance; verify transformer secondary so peak bus < 75 V.
Bus under-voltage fault – drive will not enable	Supply below the 24 V DC minimum	Measure supply; correct wiring or raise PSU voltage until 24-75 V range is met.
No torque, meter reads high	Enable opto not driven (J6 5-6 jumper out) or drive in fault state	Re-install J6 5-6 or drive opto with ≥ 3 mA; clear fault and recycle power.
No torque, meter reads low	Motor-current DIP-switches (S1-6/7/8) set incorrectly or open motor wiring	Set correct current per motor rating; re-seat and continuity-check motor cable.
Motor has holding torque but will not turn	STEP pulses missing, too narrow, or rejected by input timing	Verify indexer is issuing valid step and ground; if needed, widen pulse width or disable step filter (remove J6 1-2).
Motor rotates the wrong direction	DIRECTION polarity incorrect or A/Ā phases swapped	Correct DIRECTION logic before STEP; alternatively swap A+ / A– leads.
Doesn’t reach commanded position / stalls	Undersized supply (bus sag), resonance, or insufficient torque	Raise bus voltage, choose finer micro-step, enable Mid-Band Compensation (S1-4 OFF), and re-check sizing.
No response at high step rates	Step filter limits max frequency to 500 kHz when J6 1-2 installed; narrower pulses rejected	Remove J6 1-2 to reach 2 MHz, or reduce indexer frequency; ensure pulse ≥ 1 µs with filter enabled.
Drive stays disabled after power-up	Enable-sense jumper (J6 5-6) set opposite to system logic	Move J6 5-6 to the required sense (IN = active-low, OUT = active-high) and retest.

Part Number	Drive / Control style	Input Power	Phase Current (RMS / peak)	Micro-step choices	Stand-out features
6410-001-C-N-K	Driver-only micro-step drive (step/direction)	24 – 75 V DC	0.625 – 5 A / 7.1 A pk (switch-set)	200 – 51 200 steps/rev (binary & decimal)	Digital Electronic Damping, idle-current reduction, ≤ 2 MHz step input
6410-006-N-N-N	Same electronics as 6410-001 but “N-N-N” = no cover / no heatsink (bare-board OEM)	24 – 75 V DC	0.625 – 5 A / 7.1 A pk	200 – 51 200 steps/rev	Lightest package in family; ideal for cabinet airflow or custom heatsink mounting
6415-001-C-N-K	Oscillator + drive (on-board pots for run-speed, accel/dec)	24 – 75 V DC	5 A RMS / 7.1 A pk	200 – 51 200 steps/rev (plus analog VCO mode)	Standalone jog or velocity applications; retains all 6410 damping & fault logic
6420-001-N-K	Indexer / drive (RS-232/422/485, mnemonic program)	24 – 75 V DC	0.625 – 5 A / 7.1 A pk (DIP-set)	Fixed (200–51 200) or variable-0.01-step modes	1.8 kB NVRAM program memory, eight bi-directional I/O, can master a slave 6410
6430-001-K-N	Off-line micro-step drive with integral 120/240 VAC supply	120 / 240 VAC 50–60 Hz	0.625 – 5 A / 7.1 A pk (internal 66 V DC bus)	200 – 51 200 steps/rev	Built-in power supply, spare 66 V DC feed for second axis; same damping & idle-current options

Part Number

Fault / Error Condition	Typical Root Cause
Output-overcurrent / short-circuit fault	Phase-to-phase or phase-to-ground short on the motor leads disables drive immediately.
DC-bus over-voltage	Regenerative energy or oversized supply pushes bus > 75 V DC.
DC-bus under-voltage	Supply < 24 V DC or wiring drop; drive never enables.
Motor cable short to case	Line-to-neutral short detected at power-up or during motion.
Motor winding open / loose connector	“No-torque, meter low” symptom when one phase is open.
Enable-input not satisfied	J6 5-6 jumper set opposite to system logic or opto not driven, leaving drive disabled.
Invalid or missing STEP pulses	Noise-filtered pulses < 1 µs (filter on) or > 2 MHz (filter off) are rejected, so motor holds but won’t turn.
Direction polarity error	DIRECTION level changes too late or is inverted, causing reverse motion.
Step-size mismatch / lost steps	Indexer step resolution differs from drive DIP setting, so final position is off.
Mid-band stall / insufficient torque	Undersized power-supply voltage or damping disabled lets motor stall at mid-range speeds.

Frequently Asked Questions about 6410-001-C-N-K:

Q: What is the proper way to maintain the 6410-001-C-N-K drive?

A: The 6410-001-C-N-K drives are designed for minimum maintenance. However the housing of the drive should be cleaned regularly remove superficial dust and dirt from the drive unit. Cleaning operation should be done using clean, dry and low-pressure air.

Q: How can operators detect faults in the 6410-001-C-N-K in real time?

A: The 6410-001-C-N-K has an "Enabled" output which is on when the drive is in a normal operational state, this output is off when the drive unit is faulty. Faults in the drive can be caused by output overcurrent, bus overvoltage and low voltage supply out of tolerance.

Q: How should operators choose the transformers used with the 6410-001-C-N-K?

A: Transformers used with the 6410-001-C-N-K must be guaranteed to operated at the highest line volatge combined with the lowest line frequency that will ever be used to power the servo system. Faliure to do so can result in saturation, largue current increases and winding failure.

Q: What type of fuse should be used with the 6410-001-C-N-K?

A: The BUS MDA 10 slow blow fuse or equivalent is recommended for the 6410-001-C-N-K when it is set for 5Amps. This can change depending of the current requirement of the drive unit. The fuse should be integrated between the rectifier and the individual bus capacitors.

Q: What does the Idle current reduction function in the 6410-001-C-N-K do?

A: The idle current reduction function of the 6410-001-C-N-K is designed to reduce the phase current sent to the motor when not motion is commanded. This function reduces motor and drive heating duing stand-by operation.
