Industrial Control and Modbus Interface

The ATS22C41Q uses a serial RS485 multidrop interface with Modbus protocol for control-system communication. The available transmission rates are 4800, 9600, and 19200 bps, with an installed device address of 31. The three logic inputs provide 24 VDC control signals, while relay outputs R1 and R2 provide status functions including running, alarm, trip, stopped, starting, and ready states.

The starter accepts connection to the motor supply line or motor delta terminals. Torque control limits starting current to 3.5 In, while the adjustable output-current range is 0.4 to 1 Icl. The internal bypass changes the operating power path after starting and reduces continuous starter power dissipation.

Frequently Asked Questions

Q: What supply voltage does the ATS22C41Q accept?
A: The rated supply range is 230 to 440 VAC, with operating supply limits of 195 to 484 VAC at 50 to 60 Hz.

Q: What communication interface is provided?
A: The unit provides one RJ45 communication connection using serial RS485 multidrop and Modbus protocol at 4800, 9600, or 19200 bps.

Q: What are the physical installation requirements?
A: The starter uses forced convection cooling, has an IP00 enclosure, and is specified for vertical installation within +/- 10 deg. The supplied dimensions are 425 mm H x 206 mm W x 299 mm D.

Field Installation Guidelines

Install the starter vertically within the specified operating-position tolerance and provide the clearance required for forced-convection cooling. The IP00 enclosure does not provide protection against direct contact with conductive contamination or moisture, so the installation enclosure must provide the required environmental protection.

Route motor power conductors separately from low-level control and communication wiring where practical. Maintain appropriate separation between the RS485 communication wiring and high-current motor conductors to reduce electromagnetic coupling. Connect cable shields and protective earth according to the applicable installation standard and the system grounding design.

Verify the motor connection method before energization. The ATS22C41Q supports connection in the motor supply line or to the motor delta terminals. Confirm the supply voltage, motor current, control voltage, input logic, relay loading, and Modbus addressing before commissioning. For ambient temperatures above 40 deg C or installation altitudes above 1000 m, apply the specified current derating.
