Activation of safety functions SS1 and SS2 has repercussions on the
servo amplifier's operating mode:
SS1 when OPMODE = 0 ... 8
The drive-activated safety function "safe stop 1" (SS1) behaves the

same in all of the servo amplifier's operating modes, as ultimately the
movement is not continued. The safety card must be reset to resume
operation.
The status of the safety card (SS1 activated) is transmitted to the ser-

vo amplifier. As a result, the information is available to a higher level
control system (status word).
The transfer of setpoint values from external servo amplifier interfaces

(bus system or analogue input) is disabled.
The servo amplifier applies speed-controlled braking with the preset

braking ramp until standstill is achieved, and disables the servo am-
plifier's power element.
When the set delay time has elapsed, the safety card activates the

safety function STO. The servo amplifier cannot be restarted.
