The 7-segment display on the JCU control unit
The following table describes the indications given by the 7-segment display on the
JCU control unit. Multi-character indications are displayed as repeated sequences of
characters.
Control cable grounding
The shields of all control cables connected to the JCU control unit must be grounded
at the control cable clamp plate. Use four M4 screws to fasten the plate as shown in
below left diagram. The plate can be fitted either at the top or bottom of the drive.
The shields should be continuous as close to the terminals of the JCU as possible.
Only remove the outer jacket of the cable at the cable clamp so that the clamp
presses on the bare shield. At the terminal block, use shrink tubing or insulating tape
to contain any stray strands. The shield (especially in case of multiple shields) can
also be terminated with a lug and fastened with a screw at the clamp plate. Leave the
other end of the shield unconnected or ground it indirectly through a few nanofarads
high-frequency capacitor (e.g. 3.3 nF / 630 V). The shield can also be grounded
directly at both ends if they are
in the same ground line
with no significant voltage
drop between the end points.
Display
Meaning
L

display immediately after powering up the drive.
Normal operation – drive stopped.
(Rotating display) Normal operation – drive running.
“E” followed by
four-digit error
code
System error.
9001, 9002 = Control unit hardware failure.
9003 = No memory unit connected.
9004 = Memory unit failure.
9007, 9008 = Loading of firmware from memory unit failed.
9009…9018 = Internal error.
9019 = Contents of memory unit corrupted.
