Description

Digital Servo Amplifiers

Standard Version

Two voltage classes with large nominal voltage range
- 1 x 110V-10% … 3 x 230V+10% (SERVOSTAR 303-310, S3xx6)
- 3 x 208V-10% … 3 x 480V+10% (SERVOSTAR 341-346, S3xx0)
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 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 STO for functional safety onboard (p. 37)
Intelligent position controller onboard
Multi feedback support
Compatible with synchronous servomotors, linear motors, asynchronous motors, high frequency spindles and DC motors

Power Section

Direct connection to grounded 3-phase supply (110V-10% or 230V-10% up to 480V+10%)
TN-network or TT-network with grounded neutral point (max. 42kA symmetrical current rating)
Connection to other supply types only via isolating transformer (p.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

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

DC Bus Link Voltage

135 … 450 V DC or 260 … 900 V DC
Can be connected in parallel

Interference Suppression Filters

Integrated for the electrical supply feed and the 24V auxiliary supply voltage
C2 category per EN 61800-3 (for motor cable ≤ 10m)
C3 category per EN 61800-3 (for motor cable > 10m)

Integrated Safety

Appropriate insulation/creepage distances and electrical isolation ensure safe electrical separation (per EN 61800-5-1) between power input/motor connections and signal electronics
Equipped with soft-start, overvoltage detection, short-circuit protection and phase-failure monitoring
Temperature monitoring of the servo amplifier and motor (when using our motors and prefabricated cables)

Auxiliary Supply Voltage

24V DC
Electrically isolated with internal fusing
Powered by an external 24V DC power supply unit (e.g. with isolating transformer or uninterruptible power supply)
