Controller factors for pneumatic axes:
Menu CONTROL. PARAM.
Pneumatic axis
GAIN FACTOR
X:+0001.00
Gain factor
0.1 ... 10.0
With the gain factor you can influence the sensitivity with which the
positioning control circuit reacts to modifications of the variables"
(position, speed, acceleration).
DAMPING FACTOR
X:+0001.00
Damping factor
0.1 ... 10.0
Damping is a measure for the transition behaviour of the system from
the actual to the nominal status, especially when there are fast modifiĆ
cations to the nominal value. As a rule the system should guarantee
low−oscillation behaviour with nominal value specifications and moveĆ
ment into the target position without overswing.
FILTER FACTOR
X:+0001.00
Signal filter factor
0.1 ... 10.0
Speed and acceleration are derived from the positioning signal and
filtered to improve the signal quality. If in practice there is bad signal
quality, e.g. due to electrical interference, filtering of the signal can be
influenced by the signal filter factor. If filtering is too strong it may
destabilize control.
POS. TIMEOUT
X:01.00
Positioning timeout
0.0 ... 99.99 s
Monitors whether the positioning procedures are performed quickly
enough. The SPC200 outputs an MC fault if:
Ĉ the drive is not put into motion within the specified positioning timeĆ
out after receiving a positioning task
Ĉ the drive has exceeded the maximum permitted positioning time
(sum of the internally calculated positioning time and positioning
timeout).
If there is an MC fault the drive will be stopped. The current position
becomes the nominal position. The fault can be quitted with a new
positioning task.
Select the positioning timeout so that the positioning movements can
be completed reliably within the time selected (e.g. 0.5 to 1.0 seconds).
With the value 0.0" the monitoring of the positioning time can be
switched off.
