SIMOVERT MASTERDRIVES Operating Instructions 6-23
A recommended configuration based on user-assignable blocks (see
Appendix A) is available for firmware version V1.3 and earlier. The
configuration is subject to the restriction, however, that only master
setpoints with axis cycles in the 2
n
format can be processed. To
configure the encoder as shown in the example, the following blocks
will be needed:
♦ 2 shift multipliers/dividers (U953.36, U953.37):
For re-normalization of the master setpoint to the 15-bit setpoint of
the SIMOLINK Encoder.
♦ 2 shift multipliers/dividers (U953.38, U952.03):
For re-normalization of the zero pulse offset to the value range of
the SIMOLINK Encoder.
♦ 2 channels of double connector/connector converter (U952.88):
For conversion of setpoint and offset
♦ Modulo 2^16 adder/subtracter (U951.72):
For conversion of zero pulse offset to ’Setting value for zero pulse’
of SIMOLINK Encoder and insertion of control bit in the setpoint
telegram.
♦ 1 analog signal switch (1 word) (e.g. U950.85):
For evaluation of ’SLE control’ control bit.
♦ Fixed setpoint (1-word) (U950.39):
For insertion of control bit into setpoint telegram.
♦ Fixed setpoint (2-word) (e.g. U950.44):
For input of zero pulse offset as a fixed setpoint.
If no offset is used, two of the shift multipliers/dividers and the fixed
setpoint (2-word) will not be needed. The offset can also be specified
by means of the 2-word fixed setpoint, i.e. without shift
multipliers/dividers, if it is converted to SIMOLINK Encoder format.
Likewise, with appropriate parameterization, it is possible to substitute
the 1-word fixed setpoint for the control bit by the 2-word fixed
setpoint.
