4.1.5.2 Flow diagram
Flow diagram for quick stop function (from version 15.00.00)
 The "speed encoder signal ok" status calls for the following requirements:
• Speed sensor is set in C00495
• Speed sensor is running (no open circuit)
 The "position encoder signal ok" status calls for the following requirements:
• Position encoder is set in C00490
• Position encoder is running (no open circuit)

Although the use of 2-track HTL encoders is possible, the error detection system of the encoder always returns "OK"
as error status!
