Large supply voltage range: 3 x 208V
(with mains voltage below 300V set parameters NONBTB=3 and VBUSBAL=1.)
CANopen onboard
EtherCAT onboard
RS232 and 24V pulse direction interface onboard
Resolver-, Encoder-, AquadB Encoder-, ComCoder-evaluation onboard
Position controller onboard
STO (Safe Torque Off) onboard (up to SIL CL3, PLe)
3 frontside slots for expansion cards
Memory Card slot onboard
Synchronous servomotors, linear motors, asynchronous motors, and DC motors can
be used
Directly on grounded 3-phase supply, 208V
(with mains voltage below 300V set parameters NONBTB=3 and VBUSBAL=1.)
TN-network or TT-network with grounded neutral point, 42kA max. symmetrical cur-
rent rating, connection to other supply types only via isolating transformer, ðp.64
Overvoltage category III acc. to EN 61800-5-1
B6 bridge rectifier, integral supply filter and soft-start circuit
Single-phase supply operation possible (e.g. for setup)
Fusing (e.g. fusible cutout) to be provided by the user
Shielding All shielding connections are made directly on the amplifier
Output stage IGBT module with floating current measurement
Brake circuit with dynamic distribution of the generated power between
several amplifiers on the same DC bus link circuit.
External brake resistors if required.
DC bus link voltage 260...900 V DC, can be connected in parallel.
Interference suppression filters are integrated for the electrical supply feed and the
24V auxiliary supply voltage (with motor cable £ 10m for C2 as per IEC 61800-3, with
motor cable < 10m for C3 as per IEC 61800-3).
