SH-HC30 Height Controller System Manual
arc voltage mode, there is no decimal point position; unit: V. The first one is
described as follows:
H: the upper limit value. When the height is larger than this value, it is the

high alarm. The cutting torch can only move down and cannot move up.
L: lower limit value. When the height is lower than this value, it is the low

alarm. The cutting torch can only move up and cannot move down.
A: the set value of height; in the automatic mode, this value is used as the

given value to adjust height automatically.
E: Dead zone value (see 7.1).

D: Speed regulating zone value (see 7.1).

C: selection of detector mode (see 7.1).

b: No board falling parameter value (see 7.1)

Inspection items
Whether it is powered on
Whether the power supply voltage is normal
Whether it is locked-rotor motor
Check the power supply
The running exceeds the upper limit value of
machinery
The running exceeds the lower limit value of
machinery
Whether the cutting board is grounded reliably
Operating environment changes
Speed reduction zone value is too small
Speed reduction zone value is too big
Dead zone value is too small
Dead zone value is too big
Corrective measures
Power on
Check the power supply
Load reduction
Power on
Check the limit switch in
high position
Check the limit switch in
low position
Grounded firmly
Implement "a key height
calibration"
Increase the speed
reduction zone value d
Reduce the speed
reduction zone value d
Increase the dead zone
value E
Reduce the dead zone
