RS232 and pulse direction interface onboard
l
Restart lock STO for personnel safety onboard, ð p. 35
l
Intelligent position controller onboard
l
Multi feedback support
l
Synchronous servomotors, linear motors, asynchronous motors, high frequency
spindles and DC motors can be used
Power section
l Directly on grounded 3-phase supply, 110V
-10%
or 230V
-10%
up to 480V
+10%
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.56
l
B6 bridge rectifier, integral supply filter and soft-start circuit
l
Single-phase supply operation possible (e.g. for setup)
l
Fusing (e.g. fusible cutout) to be provided by the user
l
Shielding All shielding connections are made directly on the amplifier
l
Output stage IGBT module with floating current measurement
l
Brake circuit with dynamic distribution of the regenerated power between
several amplifiers on the same DC bus link circuit. Internal
brake resistor as standard, external brake resistors if required.
l
DC bus link voltage 135 … 450 V DC or 260 … 900 V DC,
can be connected in parallel.
l
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).
Integrated safety
l
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.
l
Soft-start, overvoltage detection, short-circuit protection, phase-failure monitoring.
l
Temperature monitoring of the servo amplifier and motor (if our motors and prefabri
-
cated cables are used).
