From version 14.00.00
Activation of special functions of the internal motor control
Setting range
(min. hex value | max. hex value)
0x0000 0xFFFF
Value is bit-coded: Info
Bit 0 Motor temp. 90° for operation
without KTY
1 ≡ Warm machine. In case the temperature tracking is
not active, a motor temperature of 90 °C is assumed.
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 ≡ 4 kHz
1 ≡ 8 kHz

Preventing a decrease of the switching frequency
Bit 5 Field/field weakening control in
500us
Cycle time for field weakening control:
0 ≡ 1 ms
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.
