8.10 Technical data for 24 V current consumption
The current consumption of the MOVIAXIS
®
units and their options depends on the
switch-on time. It is therefore not possible to specify the current consumption explicitly,
but it must be projected in relation to the switch-on time.
For more information on this, refer to the "MOVIAXIS
®
MX Multi-Axis Servo Inverter"
project planning manual.
8.11 Technical data for the braking resistors
UL and cUL
approval
Type BW... braking resistors are UL and cUL approved in conjunction with the
MOVIAXIS
®
multi-axis servo inverter. SEW-EURODRIVE will provide a certificate upon
request.
The following braking resistors have cRUus approval independent of the MOVIAXIS
®
multi-axis servo inverter:
• BW012-015-01.
• BW006-025-01,
• BW006-050-01,
• BW004-050-01,
