Parameter value not permitted for encoderless

What does F01692 mean?

A parameter value is not permitted or is incorrect for encoderless operation, indicating an invalid configuration for the current operating mode. This can lead to improper motor control and potentially unsafe conditions if speed or position feedback is compromised.

• An encoder-specific parameter (e.g., p0400 (Encoder type)) is configured with a non-zero value or an invalid encoder type, despite the drive being set for encoderless operation.
• The control mode (e.g., p1300 (Control mode selection)) is set to a mode requiring encoder feedback (e.g., vector control with sensor) while no encoder is connected or configured.
• Parameter related to encoder pole pairs or resolution is set while encoderless operation is active.
• Motor identification or tuning sequence attempted with encoderless settings, but parameters meant for sensor feedback are implicitly activated.

1. 1

   1. Verify parameter p1300 (Control mode selection) is correctly set for encoderless operation (e.g., 20 or 21 for V/f control or vector control without sensor).

2. 2

   2. Check parameters related to encoder configuration (e.g., p0400, p0404, p0408) and ensure they are either set to 0 or correspond to 'no encoder' settings.

3. 3

   3. Confirm that no physical encoder is connected to the Control Unit's encoder terminals (e.g., X130) if encoderless operation is desired.

4. 4

   4. Perform a motor identification run (e.g., p1900 = 1 or 2) after ensuring all encoder-related parameters are correctly set for encoderless mode.

5. 5

   5. Review the complete parameter set for any remnants of previous encoder configurations that might conflict with the current setup.
