We have Servo & induction motor combination printing application, When Emergency pressed or power off Induction motor suddenly stop but Servo not. want to stop servo immediately without any deceleration delay please suggest Thanks Veeresh Suranagi

Hi @veeresh.suranagi , few questions focus on servo drive: Which B&R drive do you have? Standard ACOPOS/ACOPOS P3/ACOPOSmulti… Do you have holding brake mounted on the motor? Have you configured a quickstop on the axis? Can you trace E-stop signal/actual axis position and actual axis velocity? F…

Dear Sir, It’s not a brake motor. [Servo_Motor] Its combination of Induction motor & Servo Motor application. In Below graph you can observe: 1&2 --are Servo motor --takes deceleration time to stop when Emergency & power cut. 3&4th --Induction motor & stops immediately when emergency or power…

[image] VEERESH SURANAGI: When emergency pressed: Servo motors deceleration, Velocity, Posinfo velocity made it zero (0) & cut of the servo Enable signal. pls see Valerio’s hint: Motor commutation stops immediately when STO is activated and The correct way to handle e-stop is to use th…

[image] Valerio Manenti: quickstop Hi @valerio.manenti @christoph.hilchenbac using 8EI034HWS10.xxxx-1 Servo drive. In below which category we need to use. [image] Please suggest.

Unfortunately, we cannot tell you which safety category your machine must meet. However, if regulations require that the machine be stopped as quickly as possible in the event of a safety emergency—without using a mechanical brake—then you should use the Quickstop. This ensures that the emergency …

@christoph.hilchenbac using Acp10 [image] This Quickstop need to use right? [image] In Drive Pin configuration not found Quickstop pin, found only Enable1, enable2 pins.

Hi, This Quickstop need to use right? depends on. Using ‘ncA_LIMIT’ is the simplest method, and therefore the best approach for now. In this case the drive is slowed down by the deceleration given by the values ‘limits.a2_neg’ abd ‘limits.a2_pos’. see Limit Values In Drive Pin configuratio…

Hi Sir, Thanks for ur support. I will check in shop floor machines & let u know.

Hi Sir, Thanks for your support. I am implementing the Quick stop function in servo. I need details steps or any document for doing Quick stop in logic. Then we will check simulation & then implement in machine. Regards Veeresh Suranagi

Hi @veeresh.suranagi , Christoph has already provided all links in AS Help. Maybe I can describe step by step what you have to do in case you are using mapp legacy (ACP10) and ACOPOS P3: In this example for the axis configuration I select the option ‘Init Parameter Table’ [image] [image] Ope…

Hi @veeresh.suranagi ,
check this post QuickStop function issue in B&R ACOPOS – error despite correct trigger1 signal .

Ciao
