Overvoltage category III acc. to EN 61800-5-1
Shielding connection directly on the servo amplifier
Two analog inputs onboard
CANopen onboard (default: 500 kBaud), for integration in CAN-bus systems and for set-
ting 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 STO for functional safety onboard (➜ # 38)
Intelligent position controller onboard
Multi feedback support
Synchronous servomotors, linear motors, asynchronous motors, high frequency spindles
and DC motors can be used
Directly on grounded 3-phase supply, 110V
TN-network or TT-network with grounded neutral point, 42kA max. symmetrical current
rating, connection to other supply types only via isolating transformer, (➜ # 58)
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 regenerated power between several amp-
lifiers on the same DC bus link circuit. Internal brake resistor as standard, external brake
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 electrical
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 prefabricated
cables are used).
