Error code 45, MOTOR NOT FOLLOWING
This error code is generated by the motor control. The motor control must
always receive information on the rotation of the motor from the tacho
sensor in order to rotate. If the tacho sensor is not working, the motor can
rotate for max. 10 seconds during the starting process. After this period,
the”MOTORNOTFOLLOWING”errorcodewillbeactivated.
Reasons for this code being activated can be:
• Breakinthecablesbetweenthetachosensorandthemotorcontrol
• Breakinconnectorsintachocables
• Breakinoneofthephasestothemotor(cablesorconnectors).This
error can be suspected if the motor does not rotate for 10 seconds (the
motor will not start with only two phases).
