Motor Description
1.1
Characteristics and technical data
Application
The 1FT6 series was developed for applications on machine tools with the hig-
hest demands regarding smooth–running characteristics and surface quality. In
conjunction with the SIMODRIVE 611 drive converter system with digital control,
the motors are, among other things, admirably suited for feed drives on lathes
and milling machines, machining centers, for grinding and special–purpose
machines and for woodworking.
They can be directly mounted onto feed spindles and onto gearboxes with
gears or toothed belts.
Warning
!
The motors are not suitable for direct online operation (directly connected to the
line supply).
Characteristics
Depending on the shaft height, the 1FT6 series has stall torques from 0.4 to 140
Nm at rated speeds from 1500 to 6000 RPM. They have a high overload
capability over the complete speed control range. The motors are optimized for
a low torque ripple.
Standards,
The appropriate standards and regulations are directly assigned to the
regulations
functional requirements.
Technical features
The motors are designed for operation from a 600 V DC link voltage, for
sinusoidal impressed currents. Together with the digital SIMODRIVE 611, they
form a complete drive system.
For DC link voltages which differ from 600 V (max. 700 V), the voltage limiting
characteritic is shifted as described in Chapter AL S/1.1.
Note
When the drive converter is connected, for example, to a 480 V supply, DC link
voltages are obtained > 600 V. In this case, the following restriction is valid:
Shaft heights 28, 36, 48, 63, 80 may only be utilized according to the DT=60 K
limit values.
