Technical Features 

3.4.1

 

Linear Scale Position Encoder 

M-605 stages use linear scale position encoders with 0.1 µm resolution for position detection. 

Maximum velocities of 50 mm/s can be achieved. 
The linear encoder is mounted in the center of the stage, close to the ballscrew drive to prevent 

possible cosine error. The linear encoder measures the actual position of the moving carriage 

directly, thus eliminating drivetrain errors such as non-linearity, backlash or elastic 

deformations. 
The encoder is based on an optical grating and a non-contacting read head with integrated 

signal conditioner and interpolator. 

3.4.2

 

PWM Amplifiers 

For maximum dynamic performance, the DC servo-motors are driven by high-efficiency PWM 

power amplifiers integrated into the stages. An external line-power power supply (order 

number: M-500.PS) is provided to supply the built-in amplifiers directly. This architecture allows 

high torque and high velocities while loading the motor controller with control signals only. The 

actual power is provided by the external supply. 

3.4.3

 

Travel Limit Sensors 

M-605 stages are protected against running into the hard stop by double-level magnetic limit 

sensors (Hall-effect sensors with TTL drivers) at each end of travel. 
The 

inner limit sensors

 (N1 at the negative-travel end and P1 at the positive-travel end) work 

with the controller's limit sense input lines. The TTL output signal is active high. 
The 

outer limit sensors

 (N2 at the negative and P2 at the positive end) work locally, opening a 

relay that cuts the motor current. The second-level limit switches provide for fail-safe operation 

in case the controller fails to stop the motor when the inner limit sensor is reached. 
If the outer limit switch is reached, the stage can not be operated by the controller until the 

platform is moved manually. Disconnect the motor cable or set the motor into MOTOR OFF 

state before moving the platform back into the current-allowed area via the rotary knob. 

3.4.4

 

Position Reference Signal Sensors 

Position Reference Sensors are located approximately in the middle of the operating range and 

can be used to reference the absolute position of the stage. Always approach the reference 

sensor from the same side to reach the same position. 
The reference sensor in M-605 stages provides a static signal level which depends on the 

platform position. If the platform is on the “positive side” the reference signal is +5 V, while if 

the platform is on the “negative side,” the signal level is 0 V. Most PI motor controllers and 

Windows libraries offer the option of starting a search run for the reference point using the 

current reference sensor signal to determine the appropriate direction. 
The "AutoFindReference" function allows for starting a search run for the reference signal. 

Independent at which side relative to the reference position the stage is located, this function 

always starts the stage towards the reference position.
