Chapter 7 Configure the Drive with KNX5100C Software
Servo on with Holding Brake is available starting from firmware revision 2 and
is the preferred input when using a motor holding brake.
The holding brake timing is shown in the KNX5100C software. Configure the
vertical load control feature using these steps:
1. Select Enable Vertical Load Control checkbox.
2. Verify the Enagage Delay Time for your motor (this is negative indicating
that the motor remains enabled while the holding brake is engaging).
Verify the Disengage Delay Time for your motor.
3. Navigate to Function List > Settings > Parameter Editor > Motion, and
find ID296 (P5.003); double-click the Value.
4. Use the pull-down menu for C: PFQS (Profile Quick Stop) and select the
deceleration time to use before the motor is disabled.
(AutoProtectionDecelTime ID296 (P5.003))
This value is programmable by using the PR Mode Editor > Speed and
Time Setting > Accel/Decel Time.
5. Navigate to Function List > Digital IO/Jog Control and check 'Edit DIO
Configuration', then using an available DI, use the pull-down menu to
select Servo on with Holding Brake and make this a NO type of input.
6. Verify that the motor holding brake has been selected; if it is not selected,
use the pull-down menu and associate a DO as Brake Control.
