Frequently Asked Questions (FAQ)

Q1: Can this controller handle high-speed counting and positioning?
A1: Yes. It has 4 fast inputs (100 kHz) for HSC and 4 fast outputs (100 kHz) for PTO/PWM. Supports single-phase, pulse/direction, and A/B counter modes.

Q2: What is the maximum number of expansion modules?
A2: Up to 7 relay output expansion modules. Power consumption: 17 W (with max modules) or 4.9 W (without).

Q3: How do I select between sink and source wiring?
A3: The discrete inputs are configurable as sink or source. Outputs are transistor (NPN) – use negative logic (sink). Check your field devices before wiring.

Q4: What communication protocols are supported?
A4: Ethernet port: Modbus TCP (client/server), Ethernet/IP adapter. Serial port: Modbus RTU/ASCII (master/slave). USB: SoMachine-Network.

Q5: What is the typical response time for the analog inputs?
A5: Conversion time is 1 ms per channel + 1 controller cycle. Absolute accuracy ±1% of full scale.
