Check that the conductors are securely attached to the terminals,
otherwise there exists the risk of damage. The subminiature connectors
must be screwed up!
The control voltage and monitor connections are made via a bus cable
the black core of which must be underneath.
Ensure that the line monitor end connector supplies with the power
supply module is fitted to the drive module farthest from the power supply
module.
The shielding of the command value cable and motor feedback cable, the
spindle transmitter cable and temperature sensor leads must be connected
at the main drive module.
Where a power transformer is required for the supply module, make sure
that the primary and secondary sides of the transformer are not
interchanged. Excessively high supply voltage can damage the drive.
1.4.3 Checks with the Signal Conditioning Powered Up
First, with the drive package switched off, disconnect the speed command
from the controller (X4) and remove the connections to the control inputs
and signal outputs (X2). Connect the command value box to interface X4
and connect the control inputs X2 as shown in Figure 4 of section 1.3.
Control voltage must be available at the power supply module before the
following checks can be carried out. The voltage for the signal conditioning
circuits is then available in the drive modules. The mains contactor K1
must be switched off.
At the supply module: Color: Status:
• bleeder overload red off
• power on green off
At the main drive module KDA or TDA:
• FAULT red off
• READY green off
• NO POWER must appear in the LCD display.
Check the blower and the electrical connections in the main drive
modules and the main drive motors.
The correct switching sequence is obtained when the "ready" contacts
of the supply and main drive modules are installed as per the Indramat
connection diagrams. The power can only then be applied when the Bb1
contact in the supply module is closed. Any series resistors are short-
circuited only if the Bb contact of the main drive modules closes or +24V
is present at the READY output.
