Frequently Asked Questions (FAQ)

How many hydraulic axes can one module control?

• The 1756-HYD02 controls two independent hydraulic axes simultaneously. Each axis operates with its own PID loop and configuration parameters.

What types of valves work with this servo module?

• The module interfaces with both proportional and servo valves. It generates ±10V DC analog signals to control valve position and flow rates precisely.

What position feedback devices are supported?

• The module works with Linear Displacement Transducers (LDTs). It supports absolute position ranges up to 230,000 counts for precise feedback measurement.

How fast does the servo loop update?

• You can select update rates from 500Hz to 4kHz. This flexibility allows optimization for different hydraulic system performance requirements.

Can I install this module in any chassis slot?

• Yes, the 1756-HYD02 installs in any available slot of 1756 ControlLogix chassis. The module uses electronic keying for proper identification.
