How to order KOLLMORGEN Saia PCD series I/O modules?

The frequency of the counting module is abnormal. 1. The encoder cable is too long; 2. Signal interference; 3. Improper setting of filtering time: 1. Cable length ≤ 10m (signal repeater is required for over distance); 2. Use twisted pair shielded wires (with the shielding layer grounded); 3. Set the filtering time to 1/5 of the signal period (e.g. 10 μ s for a 20kHz signal)

（2） Regular maintenance project

Standard requirements for maintenance project cycle operation content

Terminal inspection every quarter: 1. Tighten screw terminals (torque 0.7-0.8Nm); 2. Clean the terminal dust and ensure that the terminal is free from oxidation and looseness, with a contact resistance of ≤ 10m Ω

Module temperature monitoring: 1. Measure the temperature of the heat sink every month; 2. Check the fan speed (e.g. PCD2.H32x fan ≥ 2500rpm), the temperature of the heat sink is ≤ 75 ℃, and the fan has no abnormal noise

Calibration verification every six months: 1. Analog input: Input standard signal (such as 5V/10mA), read module values; 2. Analog output: Set 50% output, measure actual value deviation ≤ ± 0.5% (if exceeded, recalibration is required)

Monthly safety function testing: 1. Trigger the STO function and check if the motor torque is cut off; 2. After testing the safety relay contacts and activating STO, the motor has no torque, and the contact response is ≤ 10ms

Product lifecycle and spare parts management

Product status classification

The manual specifies the status of modules "Active", "Outphased", and "Repair phase":

The maintenance period for discontinued modules (such as PCD2.G400/G410) is until December 31, 2018, and there will be no spare parts supply thereafter;

Alternative solutions: Replace PCD2.W100 with PCD2.W380, and PCD2.H222 with PCD3.H222.

Recommended spare parts list

It is recommended to reserve 1-2 sets of key spare parts, with the following matching models:

Module type/common model/spare part model

Digital input module/PCD3.E110/PCD3.E111 (compatible and responsive)

Analog output module/PCD2.W410/PCD3.W410 (terminal upgrade)

Relay module/PCD2.A200/PCD3.A200 (same function, higher anti-interference)

Counting module/PCD2.H100/PCD3.H110 (maximum frequency increased to 100kHz)
