Description

Together with the control module, the power module forms the drive module, for
feed or main spindle applications.
The power modules can be used to operate the following motors:
S
1FT6, 1FK6 and 1FK7 servo motors
S
1FW6 built–in torque motors (direct drives)
S
1FN linear motors
S
1PH main spindle motors
S
Standard induction motors; if IM operation is selected, only inverter pulse
frequencies of 4 kHz and 8 kHz are permissible.
S
1PM hollowshaft motors for main spindle drives (direct drives)
S
1FE1 main spindle motors
S
2SP1 motor spindle
S
Third–party motors, if according to the motor manufacturer the motor meets
the requirements for sine modulation, insulation, and dV/dt resistance (see
Chapter 8.1).
For special motors with a low leakage inductance (where the controller settings
are not adequate), it may be necessary to provide a series reactor in the form of
a 3–arm iron core reactor (not a Corovac reactor) and/or increase the inverter
pulse frequencies of the converter. Motors with a low leakage inductance are,
from experience, motors that can achieve high stator frequencies (maximum
motor stator frequency
current 85 A).
>
A wide range of 1–axis or 2–axis power modules is available. These modules
are graded according to the current ratings and can be supplied with three dif-
ferent cooling techniques.
The current–related data refers to the series–preset values. At higher frequen-
cies of the fundamental waves or for higher clock cycle frequencies, ambient
temperatures and installation altitudes above 1000 m above sea level, power
deratings apply as subsequently listed.
Matched, pre–assembled cables are available to connect the motors. Ordering
information is provided in the "Motors" section of the NC 60 catalog.
Shield terminal plates are available to meet EMC requirements when using
shielded power cables.
