Power supply

WARNING

Risk of injury!

The electrical installation must be carried out by a qualified electrician.  Before installing and commissioning AX5000 servo drives please read the safety notes in the foreword of this documentation.

Notice

Destruction of the AX5000!

The connection sequence of the devices is not arbitrary. The total rated current of the device must decrease from the power supply. The order "AX5112-AX5106-AX5201-AX5103" is correct the order "AX5201-AX5112-AX5203" is wrong.

CAUTION

Hazard to persons!

Note the total current of the connected devices. According to CE the current carrying capacity of power busbars is limited to 85 A.

CAUTION

Hazard to persons!

Please ensure that the connection line for the AX5901 supply module is adequately dimensioned. The dimensioning depends on the total rated current and must comply with EN 60204-1. The connector plugs are designed for a maximum conductor cross-section of 25 mm2. A 3-phase connection must be used if the total rated current exceeds 9 A.

CAUTION

Hazard to persons!

To set up a drive system without AX5901 supply module and AX bridge please note the following: The connector plugs of the wide voltage input are designed for a maximum current of 41 A and a maximum conductor cross-section of 6 mm2. The cable configuration must comply with the requirements specified in DIN VDE 0298 Part 4 / 2003-08 and EN 60204-1.Avoid phase reversal between the devices!

    Special requirements for a drive system

    Please consult our Application Department with respect to the special requirements for a drive system with UL-Listing.

    Residual current circuit breaker

    Servo drives with built-in mains filters generate a small leakage current (fault current) due to the capacitors in the filter. This fault current is responsible for malfunctions in standard residual current circuit breakers. For this reason so-called AC/DC sensitive residual current circuit breakers must be used, which also take into account DC currents.

    X03: 24 VDC supply

    System and peripheral voltage for the servo drive is supplied via connector X3. The supply is based on two channels in order to offer an option to separate between motor stopping brakes and control electronics. Both channels are connected via a bridge as standard.

    CAUTION

    Safe operation!

    The voltage tolerances must be considered when connecting motors with stopping brake.

    Safe system stop in the event of power failure

    A power failure can lead to uncontrolled run-out of drive axes, which means that linear axes or lifting axes would hit the limit stop unbraked. The 24 VDC supply of the AX5000 has two channels, so that separate power supplies can be used for the control electronics and the brake control. This enables the supply voltage for the control electronics to be buffered via the UPS of the Industrial PCs until all axes were stopped safely.
