Bit 6 Motor ident.: No calculation C577
C578 C2864
From version 15.00.00
: Following successful motor
parameter identification, the field weakening controller
parameters for ASM servo control are calculated as well.
If these parameters are not to be calculated, bit 6 must
be set to "1".
0 ≡ Calculate parameter
1 ≡ Do not calculate parameter
Automatic motor data identification
Bit 7 If C2879 Bit1=0: C087 is warm
From version 15.00.00
, the too high slip with the
activated option "Slip calculation from motor nameplate
data" can be corrected for the ASM servo control by
setting bit 7 to "1".
1 ≡ Rated motor speed (
) is assumed for a warm
machine.
Bit 8 Suppress V/f emergency operation
From version 15.00.00
, it is internally switched to the
encoderless V/f characteristic control in case of a motor
control type with feedback and an encoder open circuit
in order to avoid impermissible motor movements.
• Exception: There will be no change-over in case of
servo control for synchronous motors (PSM).
• In order that this "V/f emergency operation" works
properly, the parameters relevant for the V/f
characteristic control (base frequency, Vmin boost,
slip compensation, etc.) have to be set correctly. As an
alternative, a motor parameter identification can be
executed as well.
• The change-over to "V/f emergency operation" is
reported via bit 4 in
and via the
bWirebreakUfLinearActive status signal at the
SB
• The setting in
is not affected by the change-
over.
The "V/f emergency operation" can be suppressed by
setting bit 8 to "1".
0 ≡ V/f emergency operation in case of encoder open
circuit
1 ≡ No V/f emergency operation in case of encoder open
circuit
