HEIDENHAIN MANUALPLUS 620 - 3.7.2 Double-row configuration

200 HEIDENHAIN Technical Manual MANUALplus 620
3.7.2 Double-row configuration
Components and cables for double-row configuration:
When using a double-row configuration, please keep the following in mind:
 The litz wires used for the DC-link connection of the power modules in the
"second row" must not be longer than 3 m.
 Litz wires with 16 mm² cross section make a DC-link current of approx. 67 A
possible. In a regenerative system, this results in approx. 35 kW of
continuous power for the system connected by these wires.
 In a nonregenerative system the resulting maximum power is
approx. 25 kW.
 Use fast-acting semiconductor fuses for protection of the UV(R) 1xxD on the
primary side.
 The length of the unit bus ribbon cable must not exceed 1 m!
 If necessary, place the MS 110 or MS 111 in the "second row" in the center
of the UMs.
 When calculating the length of the ribbon cables, make sure to include the
module width of the MS 110 or MS 111.
