13 Safe Standstill (Option)
For the digital servo amplifier JetMove 204-480, an optional integrated card for the
"Safe Standstill" and "Safe Restart Inhibit" functions can be ordered (designation of
the article: JM-204-480...-S1).
13.1 Introduction
The option "Safe Standstill" serves for safe de-energising of the motor, if personal or
material damage caused by a moving or inadvertently started motor is to be safely
prevented. This safe switching off meets the stop class 0 to EN 60204. Additionally,
by this function a safe restart inhibit has been supplied; as long as the inputs for
enable are not being controlled, any restart of the motion system is blocked.
Notes and descriptions on this can be found in this manual.
For controlling this function, there exist the terminals Enable1, COM, and Enable2.
In order to make dual-channel switch-off possible, two independent enable inputs
and ground reference have been supplied. The ground reference of the enable inputs
(COM) is potentially isolated from the ground reference of the servo amplifier (see
"Common ground" on page 71). The ground reference of enable inputs can differ by
up to +/- 100 V from the ground of the control system.

Note!
Even if the device has been equipped with the option -S1, the function of the
ENABLE input at the terminal array X10 is still active. This means the motion
system can only produce a certain torque, if this input has been connected to
24 V (against reference ground ).
