READ THIS FIRST
These instructions are intended for qualified technical personnel.
Prior commencing with any activities…
• you must carefully read and understand this manual and
• you must follow the instructions given therein.
The EC-i30 with integrated electronics is considered as partly completed machinery according to EU Directive 2006/42/
EC, Article 2, Clause (g) and is intended to be incorporated into or assembled with other machinery or other partly
completed machinery or equipment.
Therefore, you must not put the device into service,…
• unless you have made completely sure that the other machinery – the surrounding system the device is intended to
be incorporated to – fully complies with the requirements stated in the EU directive 2006/42/EC!
• unless the surrounding system fulfills all relevant health and safety aspects!
• unless all respective interfaces have been established and fulfill the stated requirements!

Repairs Be aware that you are not entitled to perform any repair on components supplied by maxon motor.

Electrostatic sensitive components
Temperature During operation, the temperature of housing, flange, or other components may exceed 60°C.
Do not engage with any work unless you possess the necessary skills.
Observe any regulation applicable in the country and/or at the site of implementation with regard to
health and safety/accident prevention and/or environmental protection.
Make sure that all associated devices and components are installed according to local regulations.
Be aware that, by principle, an electronic apparatus can not be considered fail-safe. Therefore, you must
make sure that any machine/apparatus has been fitted with independent monitoring and safety equipment. If the machine/apparatus should break down, if it is operated incorrectly, if the control unit breaks
down or if the cables break or get disconnected, etc., the complete drive system must return – and be
kept – in a safe operating mode.
• Consider any power cable as connected to live power, unless having proven the opposite!
• Make sure that neither end of cable is connected to live power!
• Make sure that power source cannot be engaged while work is in process!
• Obey lock-out/tag-out procedures!
• Make sure to securely lock any power engaging equipment against unintentional engagement
and tag it with your name!
The connected supply voltage must be between 8 VDC and 28 VDC. Permanently applied voltages
above 30 VDC will destroy the unit.
The built-in electronics can be destroyed by externally applied electronic discharges during transport,
installation, and during operation.
• Make sure to wear working cloth in compliance with ESD.
• Handle the device with extra care.
• Limit the voltage between flange and any live parts to 500 VDC

The motor produces positive torque in the selected or programmed direction. When the speed set value
is reduced or the direction changed (direction preselection version) the load is actively decelerated as to
the factory-set speed ramp.A load can be permanently decelerated.
Remark
When the load is decelerated, energy is fed back to the operating voltage supply. Thereby, the operating
voltage can undesirably increase and can damage in parallel connected consumers. Use an operating
voltage supply with feed-in possibility or a brake choppers to prevent excessive voltage surges.

As seen towards the mounting flange:
• CW = shaft turns to the right (clockwise)
• CCW = shaft turns to the left (counterclockwise)

The maximum torque the motor can produce for a short term. It is limited by the overload protection of
the electronics.
Supply current with which the peak torque is generated at nominal voltage. With an active speed controller, the supply current is not proportional to the torque, but also depends on the supply voltage. As a
result, this value only applies at nominal voltage.
