Installation and wiring specifications

1. General safety requirements

Static protection: The module contains ESD sensitive components, and a grounding wristband should be worn during operation. Refer to Rockwell document 8000-4.5.2 "Guidelines for Preventing Static Damage".

Power off operation: Before installation, all power sources of the frequency converter (including AC input, DC bus, control power) must be disconnected to avoid electric shock or component damage.

Cable requirements: Power cables must comply with NEC/VDE standards, and it is recommended to use shielded twisted pair cables (such as Belden 8760) for control cables to avoid parallel laying with high-power cables and reduce interference.

2. Key points for exclusive installation of the framework

(1) A1-A4 frame (low power)

Rail installation: Suitable for 35 × 7.5mm DIN rails, with hooks inserted and locked by rotation. The grounding resistance should be ≤ 2 Ω (detected through the metal shell of the RS-232 port).

Wiring terminal: TB1 is the power terminal (R/L1, S/L2, T/L3 input; U/T1, V/T2, W/T3 outputs), TB4/TB7/TB10 are control terminals, supporting analog I/O, pulse input, and relay output.

Input protection: Users need to provide their own fuses. For example, models with 200-240V/0.37kW require 6A Class CC fuses (North America) or 6A gG fuses (Europe).

(2) B-H framework (high power)

Fixed method: B-C frame can be installed on rails, D-H frame needs to be fixed with bolts, and reserved heat dissipation space (top/sides ≥ 152.4mm, bottom ≥ 101.6mm).

Wiring requirements: The D-H frame adopts bolt type terminals and requires dedicated wiring terminals (such as T&B COLOR KEYED) ®）， The maximum wire diameter supported is 600MCM (253mm ²), and the torque must comply with the specifications (such as 23N · m for the H frame).

Cooling system: F-H frame with forced cooling fan, fan voltage needs to be confirmed (200-240V/380-480V), H frame needs independent air duct, air volume ≥ 2600CFM.

3. Key wiring specifications

Power wiring:

AC input: R/L1, S/L2, T/L3, requiring input fuses/circuit breakers (such as 140-MN-0250 circuit breaker for 380-480V/0.37kW).

Motor output: U/T1, V/T2, W/T3, cable length must meet the requirements (e.g. maximum 500m at 125Kbps, 100m at 500Kbps), and output reactors need to be added for long distances.

Control wiring:

Analog input: ± 10V input requires differential wiring, and the shielding layer is grounded at one end (TE terminal); 4-20mA input impedance of 130 Ω, maximum load of 750 Ω.

Encoder wiring (L Option board): A/A non, B/B non signal differential access,+12V power supply (maximum 200mA), shielding layer grounded.

Grounding requirements:

The safety grounding (PE terminal) requires copper wire with a wire diameter of ≥ 1.5mm ² (16AWG) and a grounding impedance of ≤ 4 Ω.

The control signal grounding (TE terminal) is independent of the power grounding to avoid common ground interference.

System startup and parameter configuration

1. Preparation before startup

Tool preparation: HIM module (default connection to SCANPort 1), digital multimeter (measuring input voltage, within ± 10% of rated value), insulation resistance meter (measuring motor insulation, ≥ 1M Ω).

Configuration: FStart Select (216)=2, FStart Speed (217) is set to the estimated speed (such as 800rpm), and the frequency converter automatically searches and synchronizes the speed after startup.

3. Communication configuration (SCAnport/DeviceNet)

SCAnport communication:

Supports up to 6 SCAnport devices, with HIM default to SCAnport 1 and gateway modules (such as 1203-GM5) connected to SCAnport 6.

Configure SP Enable Mask (124) to allow device control permissions, such as allowing SCANPort 2 to send start stop signals.

DeviceNet communication:

The 1203-GM5 card needs to be installed, and the node address (SW2-1~6, binary encoding) and baud rate (SW2-7~8, default 125Kbps) need to be set.

Create an EDS file through DeviceNet Manager, map I/O data (such as input=motor status, output=speed reference), and set the polling rate to 50ms.
