Information/possible settings
Data type
Manual DC-injection braking (DCB)
• Detailed information on DC-injection braking is provided in the motor control
BOOL
chapter, subchapter

Note!
Holding braking is not possible when this braking mode is used!
Use the basic "Holding brake
a low rate of wear.
FALSE Deactivate DC-injection braking.
TRUE Activate DC-injection braking, i.e. the drive is brought to a standstill
by means of DC-injection braking.
• The braking effect stops when the rotor is at standstill.
• After the hold time (C00107) has expired, the controller sets the
pulse inhibit (CINH).
Ramp function generator: Maintain the current value of the main setpoint
integrator
BOOL
• The speed, for instance, of a running ramp process is immediately kept constant
when bRFG_Stop is activated. At the same time, the acceleration/deceleration
jumps to the value "0".
• For a detailed functional description see the
TRUE The current value of the main setpoint integrator is held.
Additive voltage impression
• An additional setpoint for the motor voltage can be specified via this process
INT
input.
• If there are, for instance, different loads at the motor output end, it is possible to
apply a voltage boost at the starting time.
• If the value is negative, the voltage is reduced.
• Scaling: 16384 ≡ 1000 V

Stop!
Values selected too high may cause the motor to heat up due to the resulting
current!
Additional setpoint for the motor voltage at speed = 0
• The entire voltage-frequency characteristic is provided with an offset.
INT
• Scaling: 16384 ≡ 1000 V

Stop!
Values selected too high may cause the motor to heat up due to the resulting
current!
Additional offset for the electrical angle of rotation
• If a torque is connected, e.g. dynamic acceleration processes can be generated.
INT
• Scaling: ±32767 ≡ ±180 ° angle of rotation
