6.15. “GRADIENT NOT WORKING” MESSAGE ON THE
DISPLAY
If the elevation does not work and there is no error message on the display, the elevation
movement may have been disabled in the configuration menu. For further details, refer
to paragraph 9.1.12. “Enable up/down motor”.
This error message indicates that the machine is unable to control the elevation motor. The error is
produced when the inverter does not receive pulses from the motor encoder, after having enabled it.
In this case the machine disables any movement and sets the parameter PAR 07 to 1.
On machines with low kit SW version 01.07 or lower, the error message may be caused by a
problem with the lower limit switch. In fact if the limit switch malfunctions or accidentally remains
in the open-contact state, rather than in the normally closed state, the error is not generated
immediately but will occur as soon as the elevation is increased beyond 1%. At this point, the
elevation function will be locked out and parameter PAR 07 set to 1.
If the machine uses a SW version equal or greater than 1.25.0, when the machine is switched on
again, the parameter PAR 07 is automatically reset to 0 and the machine performs the reset
procedure. If the error does not happen anymore, supposing it was generated by a noise, the
machine restarts to work properly.
In stead, if the machine uses a SW version lower than 1.25.0, when the machine is switched on
again the parameter remains set to 1, for few seconds the machine display shows again the
“GRADIENT ERROR” message, disables the elevation and allows the belt movement. To re-
enable operation of the elevation motor, parameter PAR 07 must be reset to 0, obviously after
having completed the power-on test.
It might also be helpful to refer to the theoretical explanation of the elevation control,
provided in paragraph 3.3. “Elevation motor drive”.
Carry out the checks suggested below during the elevation test phase of the machine
power up sequence. Remember to reset parameter PAR 07 to 0 every time the test fails.
