Page 28: Teach Mode = Monitoring With Learning Function
BK Mikro 7 Manual OI: BK MIKRO 7 Teach mode = monitoring with learning function Requirement: Rotary switches P1=0 and P2=0 The scanning range will be determined by a learning cycle (external control signal). This mode of operation is the typical mode for tool detection applications: The system will check for the presence of the tool at the learned position. -
Page 29: Switch Mode = Monitoring With Setting Scanning Range
Requirement: Rotary switches 0 ≤ P1 < P2 ≤ 270 Rotary switch P1 and P2 settings will define the scanning range. In this mode of operation, BK MIKRO 7 is suitable for monitoring tools with differing diameters (object monitoring) as well as for ejection monitoring (free space monitoring): Two rotary switches are used to define a scanning range which is to be monitored before each working cycle. -
Page 30: Deflection Of Wand
BK Mikro 7 Manual OI: BK MIKRO 7 5.2.3 Deflection of wand Rotation angles will be detected by scanner encoder pulses. These pulses are derived from the rotation of the motor. For scanning, a metal needle (wand) is used which, depending on the scanning force, can be deflected. -
