2. FUNCTION, CHARACTERISTICS AND CONFIGURATION
•
Sensor cable wiring
While the maximum length of the sensor cable wiring is 50 m for our conventional PY, PZ, and PE
models when a standard cable is used, the length is 30 m for the PY2 amplifier for sensor power
supply reasons (the maximum length is 25 m for the absolute encoder (ABS-E) type).
The permissible wiring distance can be extended to 50 m by using a cable with low conductor
resistance (a thick cable) or by increasing the number of wires. Contact us for details.
•
External thermal input
While our conventional PY, PZ and PE models are equipped with input terminals capable of directly
connecting contact outputs of external thermals, the PY2 amplifier is not.
To connect an external thermal output to the amplifier, set the general-purpose input terminal to the
external thermal signal input before operation.
•
AMP ready contact output
While our conventional PY, PZ and PE models are equipped with contact output terminals (AMP ready
output terminals) for magnetic contactors which control the amplifier main power on/off switching, they
are optional on the PY2 amplifier. For details, refer to "1.4 How to Read Model Numbers".
When no AMP ready output is used, turn the main power on and off using an external safety circuit.
•
Analog monitor output
While analog monitor output is ± 10 V peak for our conventional PY, PZ and PE models, it is ± 3 V
peak for the PY2 amplifier. The resolution of the PY2 is also lower than that of conventional models.
Consult with us if high resolution is required for system evaluation or other purposes.
