Bit 1 No switch-off of the brake chopper
after 4s
1 ≡ Limitation of the operating time of the brake chopper
(brake transistor) is deactivated.
Braking operation/brake energy management
Bit 2 Brake chopper off in case of trip 0 ≡ No response of the brake chopper in the "Fault"
device status.
1 ≡ In the "Fault" device status, the brake chopper is
permanently switched off without any delay.
Braking operation/brake energy management
Bit 3 Reserved (do not change!)
Bit 4 Motor ident: Switching frequency
8kHz
Switching frequency for motor parameter identification:
0 ≡ 4kHz
1 ≡ 8kHz
Preventing a decrease of the switching frequency
Bit 5 Field/field weakening control in
500us
Cycle time for field weakening control:
0 ≡ 1ms
1 ≡ 500 μs
Optimising the behaviour of the asynchronous motor
in the field weakening range
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 (C00087
) is assumed for a warm
machine.
Slip calculation for SC
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.
• 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 C01000
and via the
bWirebreakUfLinearActive status signal at the
SB LS_DeviceMonitor
.
• The setting in C00006
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
Bit 9 Optimisation of field weakening
control
Bit 10 V/f+encoder without adaptation of
voltage
