Cables and connections

Cable lengths
All inverters will operate at full specification with motor cable lengths as follows:
● Screened - 15 m (49 ft)
● Unscreened - 30 m (98 ft)
Note
Brake voltage 180VDC (400VAC with rectifier)
The brake output of the Inverter is designed to be connected directly to the coil of the
brake within the motor, that is, no rectifier module is required within the motor. For
operation of the Inverter on a 400VAC supply the brake should be rated for approximately
180VDC (400VAC with rectifier). The brake voltage is dependent on the mains supply
voltage (brake voltage = mains voltage x 0.45).
The UL approved current rating for the brake output is 600mA.
The maximum current rating for the brake output without UL is 1A.
Brake voltage 205VDC (230VAC with rectifier)
The brake output of the Inverter is designed to be connected directly to the coil of the
brake within the motor, that is, no rectifier module is required within the motor. For
operation of the Inverter on a 400VAC supply the brake should be rated for approximately
205VDC (230VAC with rectifier). The brake voltage is dependent on the mains supply
voltage (brake voltage = mains voltage x 0.9).
The UL approved current rating for the brake output is 600mA.
The maximum current rating for the brake output without UL is 1A.
For operation of a 205VDC brake the parameter P1215 must be set P1215=2.
Analog input DIP-switches
The analogue input can be configured as an additional digital input. In order to achieve this
AIN- (X15.4) should be connected to AIN 0V (X15.3) and the digital input should be
connected to AIN+ (X15.2). To make this easier a switch has been provided under the
control unit cover that, when operated, makes this connection internally. It is also possible to
select whether connection X15.1 provides a 10V (10mA) supply, normally used for an
analogue input, or a 24V (25mA) supply, normally used for a digital input. See block diagram
below for details.
Auxillary (AUX) power
To operate this product, 24V power supplies need to be provided on both the AS-i + / AS-i -
and AUX 24V / 0V pins of connector X3. When the product is connected to an AS-i network
the 24V power supply on the AS-i + / AS-i - pins is provided by the AS-i network itself. In this
case additionally a separate independent 24V power supply must be provided on the AUX
24V / 0V pins.
