Stop!
This setpoint must be below the threshold of any brake unit which may beconnected.If aconnected
brake unit is activated, the drive is braked with the maximum possible torque (Imax). The desired
operating behaviour is lost.
5. Set the setpoint on which the DC bus voltage is to be controlled:
– Set the setpoint to approx. 700 V (C0472/18 = 70 %).
Commissioning
The commissioning should be carried out with motors without load.
1. ThedrivecanbestartedwithaLOW-HIGHedgeatX5/E5.
2. Set the acceleration time Tir:
– Set speed setpoint to 100%, operate controller with maximum speed.
– Inhibit controller via terminal X5/28 (you can also use any other controller inhibit source,
CINH) and measure deceleration time until standstill.
– Set approx. 1/10 of the deceleration time in C0982.
3. Setting the retrigger time
l
In case of mains failure detection by detecting the DC bus voltage level:
– Set measured deceleration time from item 2. under C0983.
l
In case of mains failure detection via an external system (e.g. supply module 934X):
– Under C0983, set the time in which the drive is to be continued to be braked in a controlled
way for short-term mains recovery.
4. Switch off supply voltage (mains or DC bus).
The oscilloscope should display thje following characteristic:
