Command Description
CA[27]

Maximum acceptable number of iterations for auto-phasing process.
If the process fails due to overload (motion amplitude is less than CA[24]),
the auto-phasing may be repeated CA[27] times, with the current being
doubled at every iteration. If the peak current (PL[1]) is reached at any
attempt, the auto-phasing process will stop even if CA[27] allows more
iterations.

Table 3-8: CA Vector - Auto-phasing Parameters

Command Description
CA[23]

Counts per meter (any positive integer):
0: Rotary motor
1: Counts per meter in a linear motor
This parameter is not used directly by the drive but is rather stored there
for the convenience of the host.

Table 3-9: CA Vector - Miscellaneous Parameters


CA[31]

Resolution for one cycle of the analog signal.
Analog encoder cycles at one revolution x 2

CA[31]

counts/rev.

CA[31] is in the range [2..12].
Changing CA[31] resets the position counter.
For linear motors the resolution is per meter.

Table 3-10: - CA - Resolution of the Analog Encoder

The following parameters are required for Resolver, Analog Halls or Potentiometer
operation:

CA[32]

Time delay between reference output and the sampling of the signals:
Delay = TS/2 - CA[32] / 40 in [us]. This value is used to produce the
reference signal to the Resolver.

CA[33]

Resolver or Analog Halls filter frequency in [Hz], must correspond to
KV[76]-KV[84] setting. Range 300 ... 1300 Hz.
