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 Reserved
Bit 6 Reserved
Bit 7 Reserved
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
