Parameters For The Position Encoder - Festo CAMC-G-S3 Manual

2 Product description of safety module CAMC-G-S3
Data transfer / setting of the leading position encoder 1 (first encoder):
– resolver [X2A],
– SIN/COS or Hiperface encoder [X2B],
– other encoder [X2B], e.g. ENDAT, BISS.
In addition, a gear ratio for position encoder 1 between the encoder and motor can be set.
In addition, the data transfer / setting of the position encoder 2 (second encoder) is made:
– other encoder [X2B], e.g. SIN/COS, ENDAT, BISS,
– incremental encoder [X10],
– none (only if position encoder 1 is a certified position encoder).
In addition, you can set a gear ratio for position encoder 2 between the encoder and motor.
Important: The SafetyTool will warn you of impermissible encoder combinations.
For the permissible encoder combinations and the corresponding safety classification,
refer to è Section 2.2.5 (Tab. 2.7).
In the case of linear motors, FCT uses the position resolution of the measuring system and
the pole pitch ôp of the motor to calculate both a feed constant (basic information) a gear
ratio and a resolution of the measuring system relative to 2ô
This data is transferred to the SafetyTool. This means that automatic data transfer is also
guaranteed for linear motors.
Please note
Should a cross-comparison error between encoder 1 /2 occur despite successful data
transfer:
• In this case, check the gear ratio of encoder 2, as this is only monitored by the safety
module and is not integrated into the control in FCT.
2.3.3

Parameters for the position encoder

Parameter for position encoder at [X2A]
The connection is intended for resolvers [X2A]. The analogue, amplitude-modulated tracking signals of
the resolver are sampled behind the input differential amplifier in the CMMP-AS-...-M3, run internally to
the safety module and then analysed safely and via two channels there by both microcontrollers.
Parameterised / data transfer from the basic unit is not required.
