Kuhnke ARS 2340 FS 40 A Servo Drive

The ARS 2000 series servo drives support a wide range of motor types and common position encoders. By parameterizing the integrated technology functions, they can be adapted to different applications. High-precision evaluation of external signals within the drive enables the shortest possible cycle times.

Technology Functions

Positioning: Whether linear, jerk-limited or torque-limited, motion tasks are carried out with the integrated positioning control.

Path program / Linking: All 256 positioning sets can be linked together, so that complex positioning tasks can be solved without an external control system. In addition, digital inputs allow conditional branching.

Flying saw: By integrating the flying saw function into the drive, short cycle times and high accuracy are achieved.

Electronic gear / Synchronization: Position-synchronous or speed-synchronous motion of different drives with variable gear ratios can be quickly parameterized via the software assistant.

Cam disk (CAM disk): Together with the integrated virtual master and synchronization, the electronic cam can be used to coordinate multiple drives.

Linear motors: Special methods for determining the commutation position and the corresponding monitoring functions allow linear motors to be operated without commutation information.

Rotary table: Various rotary axis modes are available for rotary table applications. These can be combined with the cam disk and the electronic gear.

Switching cams: Switching cams linked to the position trigger, rotor position trigger and cam disk can easily be parameterized and assigned to digital outputs.

Safety Functions

STO – Safe Torque Off: Disconnection of the drive’s power supply in accordance with EN 61800-5-2. This function ensures that the drive can no longer generate power.

SS1 – Safe Stop 1: The drive is braked independently to a standstill within a defined time using a defined braking ramp, after which the power supply is safely switched off. SS1 type C is supported.

SOS – Safe Operating Stop: Used when the motor position or axis position must be actively maintained and safely monitored.

SS2 – Safe Stop 2: The drive is braked independently to a standstill within a defined time using a defined braking ramp. When the defined time elapses, SOS (safe operating stop) is triggered. All three variants defined in the standard are supported.

SLS – Safely Limited Speed: Prevents the motor from exceeding the defined speed limit.

SSR – Safe Speed Range: Used when the drive’s speed must be kept within a defined range.

SBC – Safe Brake Control: Provides a safe output signal to control external motor brakes. It prevents unwanted movement in the torque-free state. An external holding brake with its own power electronics can also be controlled via the safe outputs.

SSM – Safe Speed Monitor: Monitors the drive’s speed within defined limits. When these limits are exceeded or fallen below, a safety-related signal output is triggered.

SDI – Safe Direction: Ensures that the drive can only move in the defined direction.

Connection

Fieldbus interfaces: CANopen, Ethernet, EtherCAT, PROFINET, PROFIBUS.

Encoder interfaces: EnDat 2.2, HIPERFACE®, HIPERFACE DSL®, incremental encoder, resolver.
