APM9B0CTLY6 is the control module for the Altivar Process Modular range, designed to pair with an ATV900 regen drive in the 500-690 V class. It runs the drive logic, fieldbus, and safety functions — separate from the power section, so you can swap a control board without pulling line power. Supply for the digital inputs is 24 V DC (19-30 V), and the STO circuit gets its own 24 V DC rail (21-27 V) with SIL 3 rating. The module also provides a 10.5 V DC reference for a 1-10 kΩ potentiometer.
Fieldbus & I/O
Communication is dual-stack: Ethernet/Modbus TCP at 10/100 Mbit/s (RJ45 on the remote terminal) and a separate RS-485 serial link at 4.8-38.4 kbit/s, RTU framing, slave addresses 1-247. The Ethernet port handles both IP and TCP frames, autonegotiating half/full duplex. Sixteen preset speeds are selectable via discrete inputs — useful for multi-speed applications without reconfiguring the bus.
Environmental & Mounting
IP00 open-frame, rated for pollution degree 2. Ambient operating range is -10 to 40 °C without derating, 40-50 °C with derating. Storage from -40 to 70 °C. Vibration resistance: 1.5 mm peak-to-peak at 2-13 Hz, 0.5 gn at 13-200 Hz. Shock rated at 7 gn for 11 ms. Altitude derating starts at 1000 m — 1 % per 100 m above that. Humidity 5-95 % non-condensing.
