Code 231-8B40: No drive release %1

[Cause of error] - Inverter not ready - No pulse release for the power module - Uz too high - Power-fail signal active - With M controls: I32 input inactive - With P controls: Drive enabling at X50 inactive In addition, for 246 261-xx (digital current controller): - For the given axis an illegal motor model (e.g. linear motor) was selected. - The CC receives a "Drive on" command for a nonexistent axis. - The power module is not ready when the field orientation starts. Readiness of the power module is detected through the Ready signal on the PWM cable. - The power module is not ready when the current controller adjustment begins. [Error correction] - Inform your service agency - Check the activation and wiring of the pulse release - Check Uz - Check the emergency stop circuit - For a non-regenerative system: Is the braking resistor connected? - For a regenerative system: Is the energy recovery activated? - Check the cable ground and shield - Exchange the power module - For SIEMENS power converter (inverter): Exchange the interface card - Exchange the drive control board
