Issue Number: 5
6.16 M70X/HS7X Position feedback
connections
The following functions are provided via the 15-way high density D-type
connector on the drive:
•
Two position feedback interfaces (P1 and P2).
•
One encoder simulation output.
•
Two freeze trigger inputs (marker inputs).
•
One thermistor input.
The P1 position interface is always available but the availability of the P2
position interface and the encoder simulation output depends on the
position feedback device used on the P1 position interface, as shown in
Table 6-29.

The Safe Torque Off function may be used in a safety-related application in
preventing the drive from generating torque in the motor to a high level of
integrity. The system designer is responsible for ensuring that the complete
system is safe and designed correctly according to the relevant safety
standards. If the Safe Torque Off function is not required, these terminals are
used for enabling the drive.
