Function description 4 Function description 4.1 Introduction Proximity switches or rotary encoders record measured values, which are evaluated in the speed monitor PNOZ s30. There are 9 monitoring functions (F1 ... F9), which are performed simultaneously. Up to 16 different parameter sets (P0 ... P15) for the monitoring functions can be selected via the select inputs. Configuration of the monitoring functions is menu-driven, using a rotary knob. The outputs switch depending on the configuration.
Function description CAUTION! The individual blocks are galvanically isolated from each other: If possible, the connections for the various earth potentials (GND, S21, Y30 und A2) should not be connected on the PNOZ s30 but should be connected directly to the GNDs on the connected units, otherwise noise susceptibility may be increased significantly (conductor loops are not permitted).
Function description Speed range With range monitoring, the output switches off if the rotational speed (velocity, frequency) is outside the configured range. Timing diagram for speed range monitoring: Position Position monitoring is activated via a rising edge at the start input.
Function description Timing diagram for position monitoring: v Position window Configured window width s Reference position (rising edge at S34) F2 A B s Position A B Reference position (rising edge at S34) If the position moves outside the configured range, position monitoring is reset and the assigned outputs are switched off. Position monitoring can be restarted via a rising edge at the start input A max. of 4 positions can be configured to be monitored simultaneously.
Function description If an output has been switched off, it cannot switch back on again until the drive has been run in the right direction up to the tolerance value. Please note: } Direction monitoring is always active, irrespective of whether it is used in the selected parameter set. } Direct.Right and Direct.Left are active when the PNOZ s30 is started up. } Direction cannot be detected if proximity switches are used.
Function description Start modes You can choose between the following start modes: } Automatic start If an automatic start is configured, the output switches on automatically if the speed does not reach the limit value, for example. } Monitored start with rising edge If a monitored start with rising edge is configured, the output switches on if the speed does not reach the limit value and then a rising edge is detected at S34.
Function description 4.3.1 Timing diagram for speed monitoring Configuration in the example: 4.4 } Switch function: F2 } Assigned output: Rel.
Function description The switch functions are monitored simultaneously. Each of a switch function's 16 parameters can be configured as } Standstill limit } Speed limit } Upper or lower limit of speed range } Right-hand direction monitoring } Left-hand direction monitoring } Position monitoring 1 to 4 with width of position window 1 to 4 Exactly one switch function can be assigned to each output. The same switch function can be assigned to several outputs.
Function description For documentation and a better overview of the device settings, we recommend that you fill in this configuration overview before setting the device parameters (link to form, see "Create configuration overview" chapter). 4.4.1 Select Inputs The parameter sets are selected via the 4 select inputs SEL1 (Y10), SEL2 (Y11), SEL4 (Y12), SEL8 (Y13). Only one of the configured parameter sets can be selected.
Function description Parameter set Signal states of the select inputs SEL 8 (Y13) SEL 4 (Y12) SEL 2 (Y11) SEL 1 (Y10) P1 0 0 0 1 P2 0 0 1 0 P4 0 1 0 0 P8 1 0 0 0 When using these 4 parameter sets, the following safety features are met: If there is an error when activating the select inputs, such as } Short circuits and shorts between contacts } Open circuit } Input drift a parameter set other than P1, P2, P4 or P8 is selected.
Function description When using the expanded parameter sets, please note: If an open circuit occurs when the select inputs are activated, the system will switch to a parameter set with a lower number (e.g. P7 -> P3 if an open circuit occurs at SEL4). The limit values for the switch functions should therefore be entered in ascending order. (Parameter set P0 -> lowest values, parameter set P15 -> highest values). Delay on the select inputs A reaction time can be entered for the select inputs.
