1632
Input of response threshold of DC link voltage. In conjunction with machine data "Response
voltage generator axis" (MD 1631), this data defines the voltage range for the upper threshold
of the two-step controller for generator operation.
Note:
This machine data is described under the additional function "Extended shutdown and
retraction (G420...G426)", see Programming Guide 840C.
1633
Input of cutout threshold of DC link voltage. If the voltage exceeds this threshold value, the
motor switches from generator mode back to normal operation.
Note:
This machine data is described under the additional function "Extended shutdown and
retraction (G420...G426)", see Programming Guide 840C.
1634
Input of response threshold of DC link voltage; if the voltage drops below this value,
emergency retraction responses are initiated according to the operating modes selected in
machine data "Drive modes emergency retraction" (MD 1636).
Note:
This machine data is described under the additional function "Extended shutdown and
retraction (G420...G426)", see Programming Guide 840C.
1635
Input of minimum DC link generator speed. Bit 3 in the ZK2 register is set if the speed drops
below the value set here. This message is output to inform the NC that the drive operaing in
generator mode (MD 1636) has reached a speed at which the NC should initiate an
emergency retraction.
Note:
This machine data is described under the additional function "Extended shutdown and
retraction (G420...G426)", see Programming Guide 840C.
