3.5.4.3 SS1 Ramp

NOTICE

The SS1 Ramp function can only be used when an
encoder is connected to the safety option. 

This Safe Stop type allows access to the hazard area
immediately after motion is detected as stopped rather
than waiting until a specific time has elapsed.

The safety option monitors the following functions

Braking ramp 

-

In the MCT 10 Set-up Software Safe
Plug-in, the braking ramp is specified
and monitoring is activated. The braking
period depends on the speed of the
motor when braking is started. The
braking ramp can be monitored via a
maximum speed error specified in the
MCT 10 Set-up Software tolerable in

42-45 Delta V

.

Braking ramp in normal operation

-

The frequency converter starts with the
configured braking ramp when safety
function Safe Stop 1 has been activated.
Once the speed is at zero speed limit,
Safe Torque Off is activated. 

Safety function Safe Torque Off is activated when
the configured limit value for the position error is
exceeded

A standstill threshold Zero speed (

42-46 Zero Speed

) for

activating the safety function Safe Torque Off can be
specified in MCT 10 Set-up Software.

Safety function Safe Torque Off is activated when zero
speed is achieved.

Prerequisites for normal operation

Input DI1 or DI2: "1" Signal (+24 V DC)

S37 output: "1" Signal (+24 V DC). The safety
option is ready for operation

A 1/0 transition at the selected DI1 or DI2 input activates
the safety function.

Signal status of the inputs DI1 and DI2

The Safe Stop 1 ramp starts when one of the 2 inputs is
set to “0”. The safety function Safe Torque Off is activated
once the braking ramp has reached zero speed. 

3.5.4.4 SS1 Ramp Slope

For the stopping process, the safety option initiates a stop
signal to the frequency converter and monitors the
controlled braking by monitoring the braking ramp. The
admissible deceleration ramp is specified in

42-44 Deceleration Rate

. The frequency converter must

decelerate at least with the steepness of this deceleration
ramp in the event of a Safe Stop 1 request from the safety
option, even under heavy load. If the frequency converter
does not fulfill the admissible deceleration ramp during a
Safe Stop 1 requested by the safety option, a Safe Torque
Off is triggered immediately. The motor then performs an
uncontrolled stop. This action prevents the frequency
converter from continuing to run or even accelerating in
the event of an error.
