Installation Guide
6. Install the drive following the numbered steps in the Illustrations section. Certain illustrations/steps pertain to specific frame
designations and are marked as such. If the illustration or step applies to all variants, the 2nd character in the frame designation
is replaced with an x. For example, Fx09 indicates FA09, FB09a, FB09c, FK09a, and FK09c. In instances where FK09 or FK10 frame
designations are used, the illustration/step includes both the standard height (a) and extended height (c) variants.
a. Attach the components from the accessory bag to the drive (illustration step 4).
b. Mount the drive on or against a solid, non-combustible mounting surface such as concrete or metal (illustration step 5). If
configured with the heat sink access panel option, provide clearance for the access panel.
FK09a/FB09a, FK09c/FB09c, and FK10a/FB10a can be free-standing if installed with the optional pedestal kit.
c.
Ensure proper cooling by providing necessary clearance around the drive. Wall mounting require 225 mm (8.9 in) top and
bottom clearance, while floor-mount installations require 225 mm (8.9 in) top clearance only.
d. Create the openings in the cable entry plate (illustration step 6).
e. Identify the terminals for functional extensions, fieldbus, power, and ground connections (illustration step 7).
f.
Install the control wiring (illustration step 8).
g.
Install the motor, mains, and PE ground wiring (illustration step 9).
h.
Route the control cables (illustration step 10).
7.
Securely fasten the cover to the drive.
8.
Perform initial drive and motor setup. Consult the iC7 Series Industry Application Guide.
9.
Configure the fieldbus. Consult the iC7 Series Fieldbus Application Guide.
Functional Safety (Safe Torque Off)
1.6
The drive is shipped with all safe inputs de-energized. Without extra wiring to the safe I/O terminal blocks (X31 and X32), the STO
function is always active and the motor will not turn. For more information, refer to the iC7 Series Functional Safety Operating Guide
(136R0268).
To disable the STO function, install jumper wires to terminals X31 and X32. See step 7.
l
To use the STO function, wire a safety device to 1 or both of the safe I/O terminal blocks. See step 1. To prevent erroneous faults or
l
warnings from occurring, any unused safe I/O terminal blocks must be disabled using jumper wires or a jumper clip. One jumper clip
is included in the accessory bag.
RESIDUAL ROTATION
The STO function can be used for asynchronous, synchronous, and permanent magnet motors. Two faults can occur in the
power semiconductor of the drive. When using synchronous or permanent magnet motors, a residual rotation can result from
the faults. The rotation can be calculated to angle = 360/(number of poles). The application using synchronous or permanent
magnet motors must consider this residual rotation and ensure that it does not pose a safety risk. The situation is not relevant for
asynchronous motors.
A successful commissioning test of the STO function is required after the initial installation and after each subsequent change to
the installation or application involving the STO.
