bWirebreakUfLinearActive
BOOL
(from version 15.00.00)
Status "V/f emergency operation due to encoder open circuit active"
• The internal change-over to "V/f emergency operation" can be suppressed by
setting bit 8 to "1" in C02864/1
.
TRUE Due to an encoder open circuit, it is internally switched to the
encoderless V/f characteristic control in order to avoid impermissible
motor movements. This does not influence the setting in C00006
.
bSlpsmSpeedopen
LoopControl
BOOL
(from version 17.00.00)
Implementation of an own flat ramp in the open-loop controlled operation of the
SLPSM.
Setting a flat ramp in the open-loop controlled operation and a steep ramp in the
closed-loop controlled operation serves to achieve a considerably higher
acceleration of the entire drive.
TRUE Open-loop controlled operation of the SLPSM is active
FALSE Open-loop controlled operation of the SLPSM is not active
