Safety and operational standards

（1） Personnel qualification requirements

Transportation: Personnel who need to master the operation of electrostatic sensitive components;

Unpacking and installation: Electrical professionals;

Debugging: Professional personnel with knowledge of electrical and drive technology must comply with IEC 60364/60664 and national safety regulations.

（2） Key safety warning

Risk of electric shock: During equipment operation, there is a high voltage of up to 900V. After power failure, dangerous voltage may remain in the capacitor. It is necessary to wait for at least 5 minutes to confirm that the DC bus voltage is below 50V before operation; It must be reliably grounded (PE bus), otherwise it may cause fatal electric shock.

Hot air hazard: The surface temperature of the equipment may exceed 80 ℃, and it needs to be cooled to below 40 ℃ before touching to avoid burns.

Automatic restart risk: When the parameter AENA is set to 1, the device may automatically restart after power on, voltage drop, or power failure recovery. Warning signs should be posted and the dangerous area should be powered on when no one is present.

Prohibited scenarios: Not suitable for explosive environments, corrosive/conductive environments, non grounded/asymmetrically grounded power grids (voltage>240V), and ship/offshore applications; Using a servo amplifier alone to control the brake cannot guarantee functional safety and requires additional mechanical braking.

（3） Operation restrictions

It can only operate in a closed distribution cabinet, with an ambient temperature of 0-45 ℃ (rated 2.5%/K for 45-55 ℃) and an altitude of ≤ 1000m (rated 1.5%/100m for 1000-2500m);

Only use copper wire for wiring, and the wire diameter must comply with EN 60204 or NEC 310-16 standards (60 ℃/75 ℃ column).

Installation process

（1） Mechanical installation

Installation position: Vertically installed on the conductive grounding mounting plate, with reserved heat dissipation space around (such as 601-610 width of 70mm, above ≥ 40mm, below ≥ 70mm);

Fixing method: Use M5 hexagon socket screws (EN 4762) with a torque of 3.5Nm;

Protection requirements: Avoid approaching equipment with strong magnetic fields. The distribution cabinet should be forcibly ventilated to ensure that the ambient temperature is ≤ 45 ℃.

（2） Electrical installation

Wiring specifications: Power lines and control lines should be wired separately (spacing ≥ 200mm), motor cable length ≤ 25m (motor choke coil 3YL should be added if exceeding 25m), and both ends of the shielding layer should be grounded;

Key Connection:

Main power supply (X0A/X0B): 3-phase+PE, requiring external fuses (e.g. 6AT for 601/603, 10AT for 606/610, 20AT for 614/620);

DC bus (X7): Multi axis system can be connected in parallel, with a total rated current of ≤ 40A and a line length of ≤ 200mm (shielding is required for lines exceeding 200mm);

Motor (X9): including brake control (24V, max 2A), voltage drop needs to be confirmed;

Feedback devices: resolver (X2, SubD9), encoder (X1, SubD15), shielding layer grounded through front-end shielding rail.

Grounding system: Distinguish between AGND (analog ground), DGND (digital ground), XGND (24V ground), and PGND (communication ground), and ensure reliable connection to the cabinet grounding.

Debugging and parameter settings

（1） Debugging Tools and Preparation

Software requirements: Use DRIVE. EXE software (installed on Windows system, minimum Pentium I/8MB memory), connect PC and amplifier (X6) through RS232 null mode cable;

Preliminary inspection: Confirm that the hardware version matches the manual. If the storage exceeds 1 year, the capacitor needs to be recharged (single-phase 230VAC applied to L1/L2 for 30 minutes), and the wiring should comply with the drawings.

（2） Quick debugging steps

Power on initialization: First, turn on the 24V auxiliary power supply. After 30 seconds, the display screen will show the current level (such as "3" representing 3A). If there are no fault codes (such as F02=overvoltage, F04=feedback fault), it is normal;

Software connection: Start DRIVE. EXE, select the COM port, establish communication, and upload parameters;

Basic configuration:

Basic settings: Select power supply voltage, phase loss response (warning n05/fault F19), unit (speed/position unit);

Motor configuration: Select the motor model from the database and enable the brake function (if necessary);

Feedback configuration: Select the feedback type (such as resolver/FBTYPE=0), save the parameters, and cold start;

Motor jogging: Enable hardware (X3/15+24V) and software (Shift+F12), enter "Speed" mode, set safe speed (such as 100rpm), and start jogging test.

Fault handling and maintenance

（1） Fault codes and troubleshooting

Troubleshooting measures for fault code causes

F01 heat sink overheating check ventilation, clean fan filter, reduce load

F02 DC bus overvoltage check brake resistor connection, reduce braking energy (such as extending deceleration time)

F04 feedback fault check feedback cable connection and shielding, confirm feedback type parameters

F05 DC bus undervoltage check main power supply voltage, fuse, confirm phase loss protection settings

F19 main power supply phase loss check the main power supply wiring and confirm that the input voltage meets the requirements

（2） Daily maintenance

Storage: Original packaging storage (-25~55 ℃, humidity 5-95%, no condensation), capacitor restoration is required for over 1 year;

Repair and disposal: Only the manufacturer can repair, and scrapping must comply with the WEEE Directive (2002/96/EC). Contact the manufacturer for recycling.
