Position controller on board
Safe Stop STO on board (up to SIL CL3, PLe)
3 front side slots for expansion cards
Memory Card slot on board
Synchronous servomotors, linear motors, asynchronous motors and DC motors can be
used
Power section
Directly on grounded mains supply, 3x208V-10% ... 3x480V+10%, 50/60Hz
(with mains voltage below 300V set parameters NONBTB=3 and VBUSBAL=1)
TN-network or TT-network with grounded neutral point, 42kA max. symmetrical current
rating, connection to other supply types only via isolating transformer (➜ # 68)
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 amp-
lifiers 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 24 V
auxiliary supply voltage (with motor cable 10 m for C2 as per IEC 61800-3, with motor
cable > 10 m for C3 as per IEC 61800-3).
