Installation

SIMODRIVE base line A Start-Up 2-9

● X1(U1,V1,W1) － line power feeder

Three-phase 400/415VAC line power feeder.

LED lights There are six LEDs on the front panel to indicate the current status of

each circuit in SIMODRIVE base line A. Their meanings are as follows:

● Spp (red) － +/- 15V electronical level fault

● Ext (green) － External enable signal, terminal 63 or 64 missing

● (red) － Line supply fault (single or multi-phase line supply

failure at terminals U1,V1,W1);

－ no commutating reactor, incorrectly installed or

incorrectly selected;

－ power network fault or transformer too low;

● 5V (red) － 5V level fault;

● Unit (yellow)－ module ready, DC link charged;

● U

(red) － DC link overvoltage

There is a LED on the front panel for fault diagnostics, which is located at

the bottom left of terminal X321 (see fig.2-6 for reference). It is used to

indicate Ready message.

● Ready LED:

Table 2-1 Ready LED display

LED off LED on

Effect Both axes of the 2-axes

module are enabled.

At least one axis is

disabled via the terminal or

due to a fault message.

If the LED is on for the first time of Power-On, it means the drive is not

enabled. In such case, you should check the connection of the terminals

as follows:

● Check the connection of the resolver feedback signal cables, and

find out whether the cables of motor A and B is exchanged;

● Check the connection of terminal 64 and 9;

● Check the connection of terminal 65 and 9 (PLC related, -

V380x0002.1);

● Check the connection of terminal 63 and 9.

If the sound of resonance is heard, you should reduce the Kp by

adjusting the potentiometer Kp on panel.
