Cause:
The commutation offset adjustment was started while power was down.
Remedy:
Turn power on and try again.
Cause:
The commutation offset adjustment was started while the safety lockout
was active.
Remedy:
Switch off the input for the safety lockout, X3 pin 8/9, and start again. (see
Section 7.2)
The DDS 2.1 is equipped with two analog diagnostics outputs. These
may be used to emit internal drive variables for test purposes.
The DDS 2.1 with ANALOG interface offers the possibility of selecting
two signals for analog output via the diagnostics output AK1 on pin X3.1
and X3.2 or AK2 on pin X3.3 and X3.4 (for the purpose of these signals,
see Fig. 87). This can be done using the menus "OPERATING MODES,
SCALING" or "GAIN PARAMETERS" on the operator interface.
The "velocity data scaling at the analog output [rpm/10V]" allows you to
scale the velocity data at the analog output channel 1 or 2. The unit is
[rpm/10V].
The "position data scaling at the analog output [dgr/10V]" allows you to
scale the position data at the analog output channel 1 or 2. The unit is
[dgr/10V], but it must be remembered that the total voltage range is 20
V (±10V).
The following signals can be set for output using the "→" and "←" arrow
keys to change the entries in the input fields:
"Analog output: Channel 1 →:"
"Analog output: Channel 2 →:"
– Velocity command
– Velocity actual value
– Position actual value
– Current actual value
– Motor encoder sine signal
– Motor encoder cosine signal.
