Encoder with TTL signal For the speed control of induction motors with SIMODRIVE 611 universal HRS control units, sin/cos 1 Vpp variant, TTL encoders can be connected and evaluated. The limit frequency fG can be as high as 420 kHz. The SIMODRIVE 611 universal E HRS control unit allows only one TTL signal to be passed to a higher level controller using the PROFIBUS DP. Note The actually achievable system quality with regard to speed or positioning accuracy depends primarily on the quality of the used encoders and other influencing factors, such as: the mechanical system (rigidity, backlash, mass (GD2)), and also the control–engineering configuration of motors, power, controller (interpolation and control cycles, control parameters, etc.) In practice, the previously mentioned effects mean the quality that can be achieved in a real system is significantly lower than the theoretically achievable quality.The various possibilities for indirect position and speed sensing and to position the motor shaft as a function of the drive configuration (SINUMERIK, SIMODRIVE and Motor) are shown in Table 3-6 (Chapter 3.5).


Direct position sensing

The SSI encoder is used as direct position measuring system (NC) (SSI scale/ encoder is attached to the load). In addition to this direct position measuring system, on the motor side, the speed is sensed using an incremental motor encoder. The exception is the measuring system sensing for SIMODRIVE 611D HLA, where the linear scale can be used as ”motor measuring system”. The used SSI encoders must comply with the following specification: Gray or binary–coded encoders can be used under the assumption: Error bit/alarm bit is the LSB; if, in addition, a parity bit is transferred, then this is the next to last bit. If an alarm bit is not transferred, then the parity bit is the LSB. The net (useful) information – also as parity or error bit/alarm bit – are either gray or binary–coded – but never mixed. Message frame length (including alarm and/or parity): – SIMODRIVE HLA 13 and 25 bit, – SIMODRIVE 611D from 13, to 25 bit Data format: SIMODRIVE HLA only right justified For HLA: The encoder zero point of the linear encoder (absolute value 0) must not be located in the traversing range. Transfer frequency, f: 100 or 500 kHz

Encoder power supply 

Remote/sense operation is possible with the encoder power supply for the motor measuring systems and the encoder power supplies for the measuring systems for direct position sensing (voltage controlled directly on the encoder to 5%).

The power supply voltage of the measuring system is sensed using the sense lines P sense and M sense (quasi zero–current measurement). The controller compares the measuring system power supply voltage, sensed using the remote sense lines, with the reference power supply voltage of the measuring system and adjusts the power supply voltage for the measuring system at the drive module output until the required power supply voltage is set directly at the measuring system. This means that the voltage drops across the power supply cables – P encoder and M encoder – are compensated and corrected by the encoder power supply. The reference voltage is generated from a reference voltage source and is 5 V. This means that it is possible to use cable lengths up to 50 m without having to operate the measuring systems with an undervoltage condition.
