Safety regulations (core mandatory requirements)

High Voltage Danger

After a power outage, if the capacitor still has power for ≥ 30 minutes, it must be confirmed that the voltage is less than 50V before operation.

personnel qualification

Only electrical professionals are allowed to operate and comply with IEC/DIN/VDE and local safety regulations.

Special population restrictions

Personnel with pacemakers and metal implants are prohibited from approaching the equipment and motor area.

compliance requirements

Must comply with the Machinery Directive 2006/42/EC, EMC Directive 2004/108/EC, and Low Voltage Directive 2006/95/EC.

Warning sign

Three types of warnings: high voltage, rotating components, and equipment damage caused by misoperation.

Mechanical installation

Installation environment

Vertically installed in the control cabinet, with reserved ventilation/water cooling space for air-cooled/liquid cooled models; Prohibit long-term vibration environment; When using cabinets with IP4x or higher, the STO function needs to be IP54+.

cooling method

Air cooling: forced convection, heat sink can reach 100 ℃

Liquid cooling: 3/8-inch internal thread interface, leak proof quick plug, coolant ≤ 40 ℃ and not lower than 10K in the environment, anti condensation

Size and fixation

Differentiate sizes, screw specifications (M4/M5/M8/M10), and installation spacing according to BG1-BG7 models; Multiple devices arranged side by side in power order to reduce thermal interference.

EMC installation

Good grounding metal installation plate, the paint surface needs to be scraped off the contact area; Filter and driver cable ≤ 30cm.

Electrical installation (core wiring)

1. Grounding (PE)

Star connection to the main grounding bar, leakage current>3.5mA, cable cross-sectional area ≥ 10mm ² or equal diameter to the power cord.

2. Power supply system

Control power supply: 24V DC ± 20%, connect the control power first and then use the main power to prevent misoperation.

Main power supply: shielded cable, must be equipped with B-type leakage protector; IT power grid is prohibited from use; BG5+forced inlet reactor.

Fuse: Match gG fuses according to the model, see attached table for details.

3. Overview of interfaces (by chassis BG1-BG7)

X9/X10/X44:24V control power

X11: Main power input

X12: Motor, braking resistor, DC bus

X4: Control terminals (digital/analog, STO, relay)

X2: USB 1.1 Debugging

X3: Ethernet 10/100M debugging

X6/X7: Encoder/Rotary Transformer

X13/X20/X44: Motor holding brake

X1: MMC storage card slot

4. Control terminals

Analog quantity: ± 10V, 12 bits

Digital quantity: 24V, ≤ 4.8V low/≥ 18V high

STO safety torque shutdown: ENPO (release)+ISDSH (request) dual channel, OSSD compatible, response ≈ 10ms

Relay/digital output: PLC compatible, short circuit protection

5. Encoder adaptation

Rotation → X6

SSI/EnDat/HIPERFACE/SinCos→X7

Original shielded cables must be used, and intermediate connections are prohibited

6. Motor and Brake

Shielded motor wires, grounded at both ends; PTC temperature protection connected to X5

Brake drive maximum 2A, high current requires external relay

7. Braking resistor

Feedback brake energy consumption and heat generation, choose between internal/external

External resistor needs to be connected to a temperature switch, and if it exceeds the temperature limit, the main power will be cut off

Different voltages correspond to different conduction thresholds (390/650/745/765/820V DC)

Debugging (Commissioning)

1. First debugging steps

Install DriveManager 5 software

Only power on 24V control power, complete initialization

USB/Ethernet connection to PC

Wizard configuration of motor parameters (LTi motor can download parameter library)

Power on, unlock STO, enable drive, no-load test

2. Panel operation (T1/T2 buttons+dual seven segment code D1/D2)

Status/fault code display

PA menu: Factory reset parameters, MMC card upload/download

IP menu: Ethernet IP/Subnet Mask Settings (default 192.168.39.5)

Fb menu: Bus address setting

MMC card firmware update: main. hex insert firmware , power on and long press T1+T2

3. Batch debugging

Batch copy parameters through DriveManager or MMC card; The iPLC program requires CoDeSys download.

Diagnosis and faults

Panel status code

Display the status of reset, initialization, standby, running, emergency stop, fault, etc.

fault display

Er+fault number+location code, flashing repeatedly; It can be software cleared or power off reset.

Software diagnosis

DriveManager checks device status, the last 20 faults, and parameter 31 to view detailed alarms.

after-sales support

Provide the official German phone number, email address, and work order system, including model number, serial number, firmware version, fault code, and software version.

Safety Function: STO (Safe Torque Off)

The independent safety manual states that it meets EN ISO 13849 and achieves torque free safe shutdown without the need to cut off the main power supply.
