Marker pulse is optional - this signal is only available for drive firmware version 01.16.00 and above.
** Simulated encoder output only available in open-loop
*** The encoder supply is selectable through parameter configuration to 5Vdc, 8Vdc and 15Vdc
**** Terminal 15 is a parallel connection to T8 analog input 3. If this is to be used as a thermistor input, ensure that Pr 7.15 is set to 'th.sc' (7), 'th' (8)
or 'th.diSP' (9).

NOTE
SSI encoders typically have maximum baud rate of 500kBaud. When a SSI only encoder is used for speed feedback with a closed loop vector or
servo motor, a large speed feedback filter (Pr 3.42) is required due to the time taken for the position information to be transferred from the encoder
into the drive. The addition of this filter means that SSI only encoders are not suitable for speed feedback in dynamic or high-speed applications.
