3.1 Appropriate Use
The SycoTec frequency inverters e@syDrive 4624, 4625, 4626 have been specially developed for driving
HF 3-phase asynchronous motors (ASM 3-phase) and permanent-magnet synchronous motors (PMSM).
They are used in spindles, for grinding, milling and drilling machines on machine tools, for example.
They can also be used to operate motors that are made up of motor elements, and are used, for example,
as drives for test stands or other physical-technical equipment (such as vacuum pumps, centrifuges,
optical systems etc.).
The pulse-amplitude modulation (PAM) used ensures smooth and gentle operation of the motors.
The following types of motor can be operated:
•3-phase asynchronous motor (ASM 3-phase)
•Parallel operation of ASM 3-phase is possible according to user’s requirements (please contact
SycoTec’s technical support team regarding configuration of the inverter).
•Permanent-magnet synchronous motors without sensors (PMSM)
Integrated load compensation offers consistent speed regulation and –by ensuring low currents in idle
operation –prevents unnecessary heating of the connected motors.
When the stop command is given, the connected motor is braked with the deceleration ramp.
A PC can be connected via the USB interface and used to operate and configure the system and to update
the firmware.
The frequency inverter can be operated entirely via remote control. Various inputs and outputs are freely
programmable.
3.2 Installation, Commissioning and Operation
The installation must only be carried out by qualified personnel with electrotechnical training.
The commissioning must only be carried out be specialist personnel with sufficient knowledge in the
fields of electrical engineering and drive technology.
Electrostatically sensitive components must not be touched.
The following requirements must be considered for the installation and operation of the devices:
Pollution: Clean air according to IEC 60664-1, dirt level 2
Max. operating altitude: 1,000.m (5,231 ft)
Ambient temperature: +5 to +40°C (41 to 104°F) according to EN 61800-2
Relative humidity: 5 to 85% (no condensation)
The inverter must be mounted in the control cabinet.
The protection against harmful gas, oil vapor and salty air must be ensured.
The ambient air must not contain aggressive, grinding, electrically conductive, highly flammable
substances or dust.
A sudden change in temperature and / or humidity must be avoided.
For devices with a fan sufficient spaces for the suction and discharge of cooling air must be provided to
ensure effective cooling.
Incorrect installation may result in damage of material and / or serious injury of persons.
The applicable accident prevention regulations must be followed to avoid serious injuries when working
on energized devices.
The system must be properly grounded in order to prevent serious injuries due to high currents.
The electrical installation must be carried out in according to the relevant electrical codes (appropriate
wire gauges, connections of ground conductors, etc.).
The frequency inverter supply voltage must be electrically isolated from the mains.
Ensure that the supply voltage must be equipped with an overcurrent protective device.
