Control modules
The control modules evaluate the encoders which are used with them and con-
trol (open–loop) the connected motors through the power modules. The drive
system fulfills almost every requirement of state–of–the–art drive technology as
a result of the wide range of control modules.

Drive modules with induction motor regulation

Induction motors can be operated with the drive module with induction motor
control, which is designed for drive converter operation with a 600 V DC link
voltage. The maximum motor stator frequency is 1100 Hz (for SIMODRIVE 611
universal and SIMODRIVE POSMO CD/CA: 1400 Hz). For motor frequencies
above 200 Hz or rated motor currents above 85 A, it may be necessary to pro-
vide a series inductance or increase the drive converter switching frequency.
The Dimensioning Guidelines under Section 5 must be observed.

Drive module with SIMODRIVE 611 universal

When the control module is inserted in the power module, the user obtains a
drive module which can be universally used for the various SIMODRIVE motor
systems, such as permanent–magnet synchronous motors 1FT6, 1FK6, 1FN,
1FE1 and induction motors 1PH and 1LA. The motors can also be operated
from 2–axis power modules corresponding to the power requirement. Setpoints
can either be entered as analog signal or digitally via PROFIBUS–DP. The per-
missible combinations of power modules and SIMODRIVE 611 universal are
listed in the configuring tables (NC60, Section 10, Tables 2 and 3).
SIMODRIVE 611 universal is a control module with analog speed setpoint inter-
face and optional PROFIBUS–DP interface as well as with/without positioning
functionality with motor frequencies up to 1400 Hz.
1–axis and 2–axis control modules are available with option; 2–axis versions
can also be used in 1–axis power modules.
The following encoder evaluation circuits are available on various control
modules
S
Resolvers: Pole pair numbers 1 to 6, max. operating frequency, 375 Hz,
internal pulse multiplication, 4096 x pole pair number
S
Incremental encoders with sin/cos 1–Vpp signals 1–65535 pulses, max. up
to 350 kHz, internal pulse multiplication 128 x pulses.
S
Absolute value encoder with EnDat interface the same as for sin/cos 1 Vpp
encoder, plus absolute position using the EnDat protocol.
