1.2 New features
Comparing to CHC-200E, CHC-200F has new features as follow,
1
、
Increased more indicators to shows different states of THC.
2
、
Output of collision-alarm, which is optical isolation output from THC, can be sent to CNC’s
Alarm input to freeze machine’s move. This signal is effective on both manual/auto mode.
The max output is 200mA, capable to drive most relays.
3
、
Anti-collision function. On manual/auto mode, when metal or low-conductive item like hand
touches sensor ring, THC would send out collision signal and lift torch up until no collision
exist.
4
、
When HF cable is disconnected or weakly connected, it would be indicated on the
disconnection indicator. So after installation of HF cable, just shake the HF cable, the
connection will be showed by the indicator.
5
、
Sensitive and Accuracy is increased 100%.
6
、
CHC200F uses digital logic control circuit for logic control, greatly improved anti-
interference performance.
1.3 Work elements
CHC-200F work elements: It detects the distance between Sensor ring and the cutting material
(steel, metal material) via detecting the capacitance between the two parts, and keep the two parts
at a set distance by control the DC motor move. CHC-200F is a closed-loop control system, with 4
parts: Position Signal Sensing, Signal Process, Logic Control and Motor Drive.
