Function description Monitoring functions The module's FS outputs can trigger the safety function STO or SS1 on a drive as a reac- tion to the result of the monitoring functions. The module's ST output can trigger the braking ramp of the safety function SS1 as a re- action to the result of the monitoring functions.
Function description 4.5.1 Safe speed monitoring - SSM The "Safe speed monitoring" function (SSM) monitors whether the current speed exceeds a limit value. A tolerance range may also be set for the limit values used to monitor the speed. This toler- ance range modifies the set limit values.

Function description 4.5.5.2 Reaction on SS1-M (c) The ST output O00 is shut down immediately. The FS outputs are shut down after a configured delay time (STO delay time) has elapsed. The delay time starts running with a 1/0 pulse edge at the signal for the restart interlock or at the signal for the FS-O data types.
Function description 4.5.6 Activation of safety function STO on a servo amplifier The module provides all the necessary functions to implement the safety function STO on a servo amplifier. Features: The FS outputs O01 and O02 are used to activate the safety function STO on a servo amplifier.
Function description Reaction times Maximum reaction time from the moment a monitored limit value is violated to the shutdown of outputs O0, O1, O2 is: 10 ms. Cascading: With 8 networked modules, the maximum reaction time from the moment a monitored limit value is violated to the shutdown of all networked modules is: 6 ms.

If not, the for- eign body could cause invalid signals. Please note the values stated in the sensor's technical details. For a full configuration, the maximum frequency of the sensors you are using must be entered in PAS4000 (see sensor's data sheet).
Function description The maximum frequency of the used encoders must be entered for a complete configura- tion. Pay attention to the values in the technical details. 4.10.1 Output signals Output signals TTL, HTL Single ended Differential (/Z) Operating Manual PSSu K F EI | 35 1003303-EN-03...
The adapter records the data between the encoder and the drive and makes it available to the PSSu K F EI via the socket. Pilz supplies complete adapters as well as ready-made cable with connector, which can be used when making your own adapter. The range of products in this area is constantly being expanded.
Installation Installation General installation guidelines Please refer also to the PSSuniversal Installation Manual. NOTICE Damage due to electrostatic discharge! Electrostatic discharge can damage components. Ensure against discharge before touching the product, e.g. by touching an earthed, conductive sur- face or by wearing an earthed armband. 5.1.1 Dimensions Module with connector:...
Installation Module with connector and labelling bracket: Install compact module Prerequisite: The head module must be installed. If the head module does not have an integrated power supply, a supply voltage module must be installed to the right of the head module. A base module with screw terminals may not be installed to the left of the compact mod- ule.
Page 39
Installation NOTICE Potential contact damage due to twisting! The contacts for the Module Supply and Periphery Supply can be bent by twisting the compact modules on the mounting rail. – On the mounting rail, carefully slide the compact module to the left, in parallel to the adjoining module, until you hear the lateral mounting hooks on the adjacent module lock into position [4].
Installation Install/uninstall connector We recommend that the connectors with spring-loaded terminals are wired before they are plugged in. Please note: All contacts should be protected from contamination. The mechanics of the connector are designed for 25 plug in/out cycles. Installation procedure: Plug the connector into the required connector strip until it locks into position.
Installation Install labelling bracket Installation procedure: We recommend that the labelling strips are attached to the labelling bracket prior to in- stallation. Slot the two pins on the labelling bracket into the receiving lugs on the module [1]. Check that the labelling bracket is firmly seated.

Wiring Connect/disconnect the cables We recommend you use a screw driver with a 0.4 x 2.5 mm (DIN 5264) blade! Strip the cable: Strip the cable [1] and apply a ferrule if necessary (DIN 46228/Part 1 or DIN 46228/Part Connect cable: Using the screwdriver, press the actuator button on the spring-loaded terminal down as far as it will go [2], keep it held down and insert the stripped cable into the plug connec- tion as far as it will go [2].
