The controller JC-120MC is used to control machinery, such as conveyors,
production machines, and handling machines.
Operate the controller JC-120MC only within the limits and conditions set forth
in the technical specifications. The operating voltage of the controller
JC-120MC is classified as SELV (Safety Extra Low Voltage). Therefore, the
JC-120MC controller is not subject to the EU Low Voltage Directive.
The device must not be used in technical systems which to a high degree
have to be fail-safe.
The JC-120MC is no safety-related part as per Machinery Directive
2006/42/EC. This device is not qualified for safety-relevant applications and
must, therefore, NOT be used to protect persons.
If you intend to operate the device at ambient conditions not being in
conformity with the permitted operating conditions, please contact Jetter AG
beforehand.
Depending on the life cycle of the product, the persons involved must possess
different qualifications. These qualifications are required to ensure proper
handling of the device in the corresponding life cycle.
Product life cycle Minimum qualification
Transport/storage: Trained and instructed personnel with knowledge in
handling electrostatic sensitive components.

JC-120MC Safety instructions
result in a loss of any liability claims to Jetter AG.
The original parts are specifically designed for the device. Parts and
equipment from other manufacturers have not been tested by Jetter AG
and are, therefore, not released by Jetter AG.
The installation of such parts may impair the safety and the proper functioning
of the device.
Any liability on the part of Jetter AG for any damages resulting from the use of
non-original parts and equipment is excluded.
The JC-120MC contains electrostatically sensitive components which can be
damaged if not handled properly.
To exclude damages to the JC-120MC during transport, the backplane module
must be mounted to it, and it must be shipped in its original packaging, as well
as in apt protective packaging..
Use an appropriate outer packaging to protect the JC-120MC against
impact or shock.
In case of damaged packaging inspect the device for any visible damage.
Inform your freight forwarder and Jetter AG.
When storing the device observe the environmental conditions given in the
technical specification.
The operator is not allowed to repair the device. The device does not contain
any parts that could be repaired by the operator.
If the device needs repairing, please send it to Jetter AG.
When replacing the JC-120MC, class of protection IP20 is not ensured. Do not
touch any electronic components once a module housing has been removed
from the backplane module.
If you touch the EMC clip, you may damage this clip. A damaged clip may
result in lower noise immunity.
When disposing of devices, the local environmental regulations must be
complied with.

Instructions on EMI
The noise immunity of a system is determined by the weakest component of
the system. For this reason, correct wiring and shielding of cables is of
paramount importance.
Measures for increasing EMI in electric plants:
Attach the JC-120MC to a DIN rail to EN 60715 having got the dimensions
35 x 7.5 mm.
The DIN rail must be electrically conducting and grounded by either of the
two ways:
•Directly:
•Via rear panel of the electric cabinet
Also refer to Application Note 016 EMC-compatible installation of electric
cabinets by Jetter AG.
The following instructions are excerpts from Application Note 016:
Physically separate signal and power lines. Jetter AG recommend
spacing greater than 20 cm. Cables and lines should cross each other at
an angle of 90°.
The following line cables must be shielded:
Analog lines, data lines, motor cables coming from inverter drives (servo
output stage, frequency converter), lines between components and
interference suppressor filter, if the suppressor filter has not been placed at
the component directly.
Shield cables at both ends.
Unshielded wire ends of shielded cables should be as short as possible.
The entire shield, must, in its entire perimeter, be drawn behind the
isolation, and then be clamped under the earthed strain relief with the
greatest possible surface area.
When male connectors are used:
Draw the shield, in its entire perimeter, under the shielding clamp of the
metallized connector housing (impedance shielding), respectively of the
EMC gland bushing, its greatest possible surface area being clamped
under a strain relief.
Only use metallized connectors, e.g. Sub-D with metallized housing. Make
sure that the strain relief is directly connected with the housing here as
well.

4, 8 or an unlimited number of axes
(on the CAN bus: 16 axes max.)
With 4 axes, the cycle time is 2 ms.
With 8 axes, the cycle time is 4 ms.
Up to 12 servo axes with path control (on the CAN
bus a maximum of 6 servo axes is supported)
2 Ethernet ports with integrated switch
Powerful programming language JetSym STX

Non-volatile registers:
60,000 (option -R: 120,000)

Program/data memory: 24 MB
1 serial port (RS-232/422/485)
Either 1 JX2 system bus port or 1 CAN port
(CANopen®)
1 additional CAN port (CANopen®)
Up to 16 JX3 modules can directly be added.

Real-time clock
