Message
62
Valve over-temperature
F2
F
Cause
The valve reports over-temperature (ambient temperature too high).
Measure
Provide sufficient cooling.
63
Valve jammed
F2
F
Cause
The valve piston does not move as expected.
Measure
Replace valve.
Also check the air quality (5 μ-filter and dry air).
64
Valve load voltage outside tolerance range
F2
F
Cause
The valve reports insufficient load voltage. Either the cable between the CMAX
and the valve is faulty, or the valve is defective.
Measure
Check lines on the axis string.
Check valve; replace if defective.
65
Valve operating voltage outside tolerance range
F2
F
Cause
The valve reports insufficient operating voltage. Either the cable between the
CMAX and the valve is faulty, or the valve is defective.
Measure
Check lines on the axis string.
Check valve; replace if defective.
66
Overload at digital output of valve
F2
F
Cause
The valve reports an overload on the digital output.
Measure
Check and correct the circuitry.
67
Overload at 24 V supply output of valve
F2
F
Cause
The valve reports an overload on the voltage output.
Measure
Check and correct the circuitry.
68
Preliminary warning valve over-temperature
W
F
Cause
The valve reports a high operating temperature. (Ambient temperature too high).
Measure
Provide sufficient cooling.

72
System software error
FS
Poff
Cause
Internal software error (firmware).
Measure
If possible, read diagnostic memory and save and archive the project.
Switch controller off/on and check whether error occurs again.
Contact Support.
73
Controller hardware faulty
FS
Poff
Cause
No communication possible with CMAX. Error is only shown on the display.
Measure
Switch controller off/on and check whether error occurs again.
Replace CMAX.
