4.1Introduction

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.

An interface is available to connect a contact expansion module PNOZsigma, enabling the number of outputs to be expanded.

The relay conforms to the following safety criteria:

}The circuit is redundant with built-in self-monitoring.

}The safety function remains effective in the case of a component failure.

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).

4.3Functions

The following monitoring functions can be configured:

Standstill

With standstill monitoring, the output is switched on when the value falls below the stated standstill value; if the standstill value is exceeded, the output switches off.

Speed

With speed monitoring, the output switches off when the configured value is exceeded. Timing diagram for standstill/speed monitoring:

Position

Position monitoring is activated via a rising edge at the start input. The current position is adopted as a reference position in the middle of the position window (configured window width) and the assigned output is switched on.

The output will stay switched on provided the current position is within the position window.

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. Please note:

}Active position monitoring is not restarted by another rising edge at the start input.

}Active position monitoring continues unchanged even if a different parameter set is selected, which also uses position monitoring. This also applies if position monitoring is used in a different switch function.

}Active position monitoring is reset if another parameter set is selected, which does not use position monitoring.

}Position monitoring cannot be used if proximity switches are employed.

Direction

If the direction is to be detected safely, this function must be linked to a safety contact.

}If "Direct. Right" is configured, the safety output is switched on during normal operation in clockwise rotation.

}If "Direct. Left" is configured, the safety output is switched on during normal operation in anti-clockwise rotation.

For both directions, a tolerance can be entered for the wrong direction. In other words, the drive can run in the wrong direction up to the set tolerance value, without the assigned output switching off.

Operating Manual PNOZ s30	16
1001715-EN-13

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.

Configuration in the example:

}Wrong direction in anti-clockwise rotation Max. right: 3 pulses

}Wrong direction in clockwise rotation Max. left: 3 pulses

Monitoring for broken shearpins

An additional proximity switch or an HTL signal from an additional rotary encoder can be connected to track Z to monitor for broken shearpins. These must both be configured as Z-frequency monitoring.

Hysteresis

For each switch function F1 ... F9 (with the exception of direction and position), a hysteresis can be configured. This prevents the outputs on the speed monitor from bouncing if there are fluctuations around the response value. The hysteresis becomes effective when the output is switched on:

Switch-on value = switching threshold – hysteresis For the lower range limit:

Switch-on value = switching threshold + hysteresis

Operating Manual PNOZ s30	17
1001715-EN-13

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.

}Monitored start with falling edge

If a monitored start with falling edge is configured, the output switches on if the speed does not reach the limit value and then a falling edge is detected at S34.

Switch delay

A delay time can be set for each output (see technical details). The outputs will not switch until the set time has elapsed. It is possible to configure whether the delay time is to be activated when switching on, switching off, or switching on and off.

WARNING!

Potential loss of safety function due to increased reaction time

The output switch-off delay (tdo, Off) when overspeed is reached will increase the speed monitor's reaction time by the stated value (see technical details). This must not delay the arrival of a safe condition by more than the permitted time. The configuration of the switch-off delay must be considered in the risk assessment as regards hazards, reaction time and safety distance.

Feedback loops

Feedback loops are used to monitor external contactors or relays. The corresponding feedback loop must be closed before starting.

Start-up delay

A start-up delay time can be configured, which prevents the evaluation of the encoder signals for the configured time period after the supply voltage is switched on.

Switching direction on semiconductor outputs

The semiconductor outputs can be operated in normally de-energised or normally energised mode.

Units

The values to be configured can be entered in various units. Depending on the axis type (linear or rotational axis), various units can be selected for speed and distance (see chapter entitled "Menu overview").

4.4Speed configuration

The speed monitor is configured using the rotary knob on the device.

Up to 16 parameter sets (P0 ... P15), each with a max. of 9 switch functions (F1 ... F9) can be configured to monitor various operating modes, for example.

One of the 16 parameter sets is selected via 4 select inputs SEL1 (Y10), SEL2 (Y11), SEL4 (Y12), SEL8 (Y13).

Operating Manual PNOZ s30	19
1001715-EN-13

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. With range monitoring, a range is assigned to an output (F2-F3, F4-F5, F6-F7 or F8-F9).

A switch delay and start mode can be configured for each output.

If only one parameter set is used, configure the mode "Select inputs: None". The select inputs will then be ignored.

Information

2 basic configurations are available for standard applications, for simple configuration within the display menu. A basic configuration contains limited menu functions adapted for standard applications, with partly pre-defined parameters. Further information about basic configurations can be found in this chapter, under "Basic configuration".

Example configuration:

2 parameter sets for 2 operating modes are configured:

}Set-up: P1

}Automatic mode: P2

The parameter set P1 is used to monitor a reduced speed.

The parameter set P2, "Automatic mode", is selected for speed monitoring (selection via the select inputs, see next chapter "Select inputs").

The following switch functions are configured for the parameter set P1:

}F1: Standstill 2 Hz

}F2: Overspeed: 50 Hz

}F3: Warning threshold: 50 Hz

The following switch functions are configured for the parameter set P2:

}F1: Standstill 2 Hz

}F2: Overspeed: 3000 Hz

}F3: Warning threshold: 2800 Hz

The following outputs are assigned to the switch functions:

}F1: Relay output Rel. 1

}F2: Relay output Rel. 2

}F3: Semiconductor output Out 1

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).

4.4.1Select 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.

One of the following modes can be selected in the "Select inputs mode" menu, depending on the application:

"None" mode

For applications up to PL e of EN ISO 13849-1 and SIL CL 3 of EN IEC 62061.

The select inputs are ignored. Only the parameter set P0 is configured and used. The lowest frequency (10 mHz) is automatically set for all other parameter sets.

"1 from 4" mode

For applications up to PL e of EN ISO 13849-1 and SIL CL 3 of EN IEC 62061. A maximum of 4 parameter sets can be configured and used: P1, P2, P4 and P8.

Operating Manual PNOZ s30	21
1001715-EN-13

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.

The lowest frequency (10 mHz) is automatically set for the other parameter sets (P0, P3, P5 ... P7, P9 ... P15). If one of these parameter sets is selected, an error message appears and all outputs switch off.

"All 16" mode

In this mode, the number of parameter sets can be increased to max. 16. This mode can only be used for applications up to max. PL d of EN ISO 13849-1 and up to SIL CL 2 of EN IEC 62061.

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. That way it is possible to filter out invalid signals (e.g. contact bounce or an intermediate state) that occur when switching.

4.4.2Switch functions

The following switch functions can be configured:

}Standstill

The standstill frequency is configured centrally. The standstill frequency should be the lowest frequency in the configuration.

All switch function parameters are pre-configured to the lowest frequency ex works.

}Speed

Limit values can be configured to monitor for overspeed.

Limit values should be entered in ascending order (Parameter set P0 -> lowest values, parameter set P15 -> highest values)

}Speed range

Up to 4 speed ranges can be monitored simultaneously. Configure two switch functions to monitor a range:

–F2 and F3,

–F4 and F5,

–F6 and F7 or

–F8 and F9.

The switch function with the lower number (e.g. F2) operates as the lower range limit; the switch function with the higher number (e.g. F3) operates as the upper range limit.

Both switch functions can be assigned to one or more outputs.

}Position

Up to 4 different position windows can be monitored: Position 1 ... Position 4.

Each position to be monitored can be entered as often as necessary in parameter sets P0 to P15 and switch functions F1 to F9.

}Direction

The monitoring functions "Direct. Left" and "Direct. Right" can be configured as a switch function as often as necessary.

For both directions, a tolerance can be entered for the wrong direction.

4.4.3Basic configuration

Two basic configurations are available for standard applications, for simple configuration within the display menu. A basic configuration contains limited menu functions adapted for standard applications, with partly pre-defined parameters.

4.5Input device types

4.5.1Proximity switch

}The following proximity switches can be used:

–pnp

–npn

}The proximity switches must be fitted so that at least one is always activated. In other words, the proximity switches must be fitted so that the recorded signals always overlap.

}The cable used to connect the proximity switches must be shielded (see connection diagrams in the chapter entitled "EMC-compliant wiring").

}The supply voltage of the proximity switches should be monitored via track S.
