1.6 Jetter AG in a nutshell
The company1.6.1
Jetter AG has been a competent industrial automation provider for more than 30 years. A
distinctive feature of Jetter technology is the integration of all automation functions into one system
and one programming language. This means that you will not need additional third party software
or hardware. Instead, you can meet any of your automation requirements by Jetter AG technology.
This holistic approach eliminates cumbersome software and hardware interfaces to give you an
integrated, optimally coordinated system. The result is simplified programming which grants earlier
commissioning of your systems. That will surely boost time-to-market! As early as in the nineties,
Jetter AG was the first enterprise in electronics industry vertical to consequently rely on networking
by standard Ethernet TCP/IP and by using Web technology (at Jetter AG, this is JetWeb
technology).
This made merging corporate IT network and production IT possible for the first time.
Subsequently, processes could be simplified, while forward-looking features such as remote
maintenance, could be implemented. Since the introduction of JetWeb technology thousands of
Jetter AG control solutions have been implemented in a wide range of applications in mechanical
and plant engineering - an expertise which now gives our customers the benefit of perfected
products and first-class service. Spurred by multiple success, Jetter AG keeps searching for, and
developing, new solutions and technologies to make automation still easier for you. Introducing a
new, even more powerful controller series, has been another milestone for Jetter AG proving it to
be a both competent and innovative partner in automation technology.
Jetter motors - Power in every size1.6.2
The correct choice and design of a servo motor is key to optimal drive and machine performance.
The long-term experience and the large product portfolio of Jetter AG help you find the motor most
fit for your specific application. Going with the JetMove servo amplifiers are Jetter motors featuring
DC link voltages of DC 24 to 560 V and a great selection of motor windings. The right combination
will produce the optimal speed for the application while also optimizing use of the servo amplifier's
rated current. All Jetter AG servo motors are extremely rugged 3-phase synchronous motors with
UL certification, which are available in the series JHN, JHQ, and JL.
A specific feature of JHN and JHQ motors is their automated segmented winding
technology and further optimized motor design, which result in high power density at very
low space requirements.
JHN motors are available in flange sizes 2 to 7 from 0.28 Nm to 60 Nm (flange 2 = 6-pole,
flange 3 or larger = 10-pole).
The JHQ motor series has the largest selection of flanges and encoders. From flange size
12 to 8, a torque range from 0.18 Nm to 120 Nm is supplied in 6-, 8- or 10-pole versions.
JL in classical winding technology are 6-pole motors and cover the range from 0.1 Nm
(JL1) to 115 Nm (JL8).
A large number of options for connector models, degree of protection or encoder design round off
the range and leave nothing to be desired when looking for a suitable servo motor. In addition to
the extensive range of motors, Jetter AG also offers pre-assembled and tested servo cables, as
well as ready installed suitable gear boxes. This saves you time and guarantees you a safe
system!

2 Safety advices
2.1 General information
At the time of placing on the market, this product corresponds to the current state of the art and
meets the recognized safety rules.
Besides this user manual, laws and regulations in the operator's country are relevant to the
operation of the product. The operator is responsible for complying with the directives mentioned
below:
Applicable legislation, rules, and regulations
Relevant accident prevention regulations
Accepted safety rules
EU directives and other country-specific regulations
2.2 Purpose
Intended use2.2.1
The servo motors are intended for industrial or commercial applications.
They comply with the relevant parts of the harmonized series of standards EN 60034. If in special
cases, that is when motors are used in non-industrial or non-commercial plants increased
requirements apply, these requirements must be complied with on the part of the plant.
Typical applications are robotics and handling, machine tools, packaging and food processing
machinery and similar machines.
The servomotors may only be operated within the operating and environmental conditions
specified in the documentation (installation altitude, degree of protection, temperature range,
electrical and mechanical data, etc.).
Before commissioning systems and machines in which the servomotors are installed, the system
or machine must conform to the Machinery Directive, Low Voltage Directive and EMC Directive.
The rated AC voltage of the servo motors is 170 V or 310 V. The winding isolation is rated at DC
750 V. During braking operation, for example, the DC link voltage of the servo amplifier, however,
can amount up to DC 850 V. Thus, servo motors are subject to the EC Low Voltage Directive.
Systems and machines with inverter-fed three-phase motors must meet the protection
requirements of the EMC directive. It is the responsibility of the system installer to carry out the
correct installation. Use only shielded signal and power lines. Observe the instructions of the
inverter manufacturer for EMC-compliant installation.
The servomotors may only be put into operation after the EMC-compliant installation of the overall
system.
