Shielding connection directly on the servo amplifier
Two analog inputs onboard
CANopen onboard (default: 500 kBaud), for integration in CAN-bus systems and for
setting parameters for several drives via the PC interface of one of the amplifiers
Slot for an expansion card
RS232 and pulse direction interface onboard
Restart lock -AS- for personnel safety onboard, ð p. 77
Intelligent position controller onboard
Multi feedback support
Synchronous servomotors, linear motors and asynchronous motors can be used
Directly on grounded 3-phase supply, 110V
TN-network or TT-network with grounded neutral point, 5000 A max. symmetrical
current rating, connection to other supply types only via isolating transformer, ðp.48
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
Regen circuit with dynamic distribution of the regenerated power between
several amplifiers on the same DC bus link circuit. Internal
regen resistor as standard, external regen resistors if required.
DC bus link voltage 135 ... 450 V DC or 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 EN 61800-3, with
motor cable < 10m for C3 as per EN 61800-3).
Appropriate insulation/creepage distances and electrical isolation ensure safe electri-
cal separation, as per EN 61800-5-1, between the power input / motor connections
and the signal electronics.
Soft-start, overvoltage detection, short-circuit protection, phase-failure monitoring.
Temperature monitoring of the servo amplifier and motor (if our motors and prefabri-
cated cables are used).
