Common Issues and Alarm Code Interpretation for the Solidot XB6S PTO Pulse Output Module During Use

Solidot Slice-type PTO Pulse Output Module XB6S-PT04A, which can be externally connected to stepper/servo motor drivers, drives stepper/servo motors by outputting pulses. During use, issues such as "no response" or "no movement" when issuing start or homing commands may be encountered. This article details the solutions for these phenomena.

I. Alarm Code Interpretation

The upstream data of the XB6S-PT04A includes a two-byte alarm code prompt. Once a channel generates alarm information, movements related to that alarm cannot be started, while movements unrelated to the alarm can still proceed normally. This case uses Solidot's upper computer software IO Config Tool for demonstration and explanation.

Alarm code interpretation is roughly divided into 3 steps—

1.Find the corresponding alarm code address according to the mapping address and read the corresponding value. If there is no alarm, the value is 0.

2.Open the computer's built-in calculator, switch to programmer mode, and convert the read alarm code value to a binary number.

3.The module's alarm code is a combination code; one value can contain multiple alarm messages. Interpret the converted binary numerical value in segments according to the 8421 code.

For example, the first four digits:

0001 corresponds to alarm list 0x0001 in the manual, and digits 9-12 (0110) correspond to alarm lists 0x0200 and 0x0400 in the manual.

II. Alarm Cause Analysis

1.0x0001: Starting Speed > Running Speed (Starting speed defaults to 10);

2.0x0200: Acceleration Time Out of Bound (20~5000ms);

3.0x0400: Deceleration Time Out of Bound (20~5000ms).

These three alarms are common issues when first using the XB6S-PT04A module, usually caused by the acceleration time, deceleration time, or running speed not being set.

III. Common Problem Phenomena

1.The module is successfully configured, but after issuing an action command, the module has no output action. This is often due to an alarm generation. Check the alarm code and resolve the alarm before normal operation can occur.

2.The module has no alarm (alarm code value is 0), but after issuing an action command, the module has no output, as shown in the figure below.

The alarm code for Channel 3 is 0. In this case, check if the module's brake indicator is constantly lit. If the brake light is constantly lit, the module will also have no movement. The module requires the origin signal and brake signal wiring to be consistent. During use, if the origin signal is set to a normally closed wiring method but the brake signal is not connected, this problem will occur.
