Pn - Parameter
33
ANTRIEBSTECHNIK
With DC-braking the motor is not decelerated by the ramp. Quick braking occurs with
d.c. voltage, which is given onto the motor winding. Pn. 8 specifies, whether DC-
braking is triggered.
Value Condition
0 No DC-braking
1 Switch off the dir. of rot. and reach f = 0 Hz (LS)
Braking time = Pn.11, as long as no dir. of rot. is given
2 Switch off the direction of rotation
Braking time = (Pn.11 * actual frequency) / 100 Hz
3 Change of rotation
Braking time = (Pn.11 * actual frequency) / 100 Hz
4 Switch off the direction of rotation
and actual value < DCB Start-frequency (Pn. 9)
Braking time = (Pn.11 * actual frequency) / 100 Hz
5 Actual value < DCB Start-frequency (Pn. 9)
Braking time = (Pn.11 * actual frequency) / 100 Hz
6 Setpoint < DCB Start-frequency (Pn. 9)
Braking time = (Pn.11 * actual frequency) / 100 Hz
Restart 1st when the setpoint > DCB Start-frequency (Pn. 9)
7 Activation of a digital input (I1 .. I2, see di. 3/4)
Braking time = (Pn.11 * actual frequency) / 100 Hz
Restart 1st, when the input is activated
8 Activation of a digital input (I1 .. I2, see di. 3/4)
Braking time = time, which the input is active
9 Switch on the modulation (control release and dir. of rotation)
Braking time = Pn.11
This sets the frequency level for Pn. 8 = 4 .. 6.
Setting range: 0 .. 409.5875 Hz
Resolution: 0.0125 Hz
Specifies the maximum negative anode potential and d.c. voltage. The negative anode
potential is, if necessary, reduced dependent on the rate of utilization.
Setting range: 0 .. 25.5 %
Resolution: 0.1 %
Adjustment information: When the DC brake is switched on, the load may not exceed
110% (only for a short time in the starting torque of the DC
brake). The DC brake voltage (Pn.10) must be limited to
max. 110% if the load exceed 110%.
The length of the braking time is dependent on the braking mode (see Pn.8). With
some modes the braking time shortens and/or lengthens itself depending on the actual
frequency. It is limited to max. 100 s.
Setting range: 0 .. 100 s
Resolution: 0.01 s
