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.
 Motor control board defective
 PWM cable defective
 Noise pulses
 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 grounding and shielding of the
cable.
 Exchange the power module.
 For SIEMENS power converter (inverter):
Exchange the interface card.
 Exchange drive control board.
 Check the control and cabling of the pulse
release.
