Allen Bradley 1336 IMPACT AC Inverter

(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

Hardware inspection: Confirm correct wiring (no AC input/output terminals, no short circuits), clean fan/heat sink, and securely install encoder (if any).

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).

Parameter recording: Record the frequency converter model, motor nameplate data (power, voltage, current, speed, number of poles), and encoder PPR value for rapid debugging in the future.

2. Quick start process (via HIM)

(1) Power on and HIM operation

After powering on, the HIM displays the startup interface. Press any key to enter "Choose Mode" and select "Start Up".

Quick Motor Tune:

Select 'Enter Nameplate Motor Data' and enter the motor HP, voltage, current, etc Hz、 Speed and number of poles.

If using an encoder, select "Encoder" and enter the PPR value; Choose the braking method (dynamic braking/magnetic flux braking, etc.).

Press the START button to test the direction of motor rotation. If it is reversed, adjust the motor phase sequence; Run self-tuning (inductance, resistance, flux current, inertia test), and display "Tune Complete" after completion.

Config Digital Section:

Configure relay output (such as setting Relay 1 to "At Speed" and threshold to 95% rated speed).

Configure L Option mode (such as mode 5 supporting MOP manual potentiometer control) and stop type (coasting/ramp/current limit stop).

Configure Analog Section:

Link speed reference (e.g. Analog In1 link Speed Ref 1, Scale set to 2.0 to achieve ± 10V corresponding to ± 100% speed).

Configure analog output (such as Analog Out1 linked to Motor Speed, Scale set to 0.5 to achieve ± 100% speed corresponding to ± 5V output).

Functional applications and advanced controls

1. Basic control functions

Start stop and speed regulation:

Local control: Use the START/STOP button on HIM to start and stop, and the Up/Down button to adjust the speed; Remote control: Speed regulation through analog input (such as 4-20mA) or SCANPort signal.

Jog Speed 1 (38) is set to 10% rated speed, triggering Jog input to achieve jog control.

Braking control:

Dynamic braking: An external braking resistor is required, with Bus/Brake Options (13) set to bit10=1 and Regen Power Lim (76) set to 50% (adjusted according to the resistor capacity).

DC Braking: The DC Brake Current (79) is set to 30% of the rated current, and the DC Brake Time (80) is set to 2 seconds, suitable for rapid shutdown.
