Electrical Connection

The pulse-train output module FM562 can be connected to the following devices via the I/O bus connector:

  • S500 PROFIBUS and PROFINET bus modules (e. g. CI501-PNIO, CI541-DP)
  • AC500 CPUs (PM5xx)
  • Other AC500 I/O modules

Note

The I/O module must not be used as a decentralized communication interface module with DC505-FBP and CI590-CS31-HA bus modules.

Note

The module must not be used as a decentralized communication interface module at CI58x-CN or CI59x-CS31.

The electrical connection is carried out by using removable 9-pin and 11-pin terminal blocks. These terminal blocks differ in their connection system (spring terminals or screw terminals, cable mounting from the front or from the side). For more information, please refer to the chapter Terminal Blocks for S500-eCo I/O Modules TA563-TA565 - Terminal Blocks. The terminal blocks are not included in the module’s scope of delivery and must be ordered separately.

The following block diagram shows the internal construction of the digital inputs and outputs:

Note

The 2 SGND signals are internally interconnected.

The assignment of the terminals:

Terminal Signal Description
1 C0..1 Input common for signals I0 and I1
2 I0 Input signal I0 (axis enable and limit switch)
3 I1 Input signal I1 (stop)
4 O0 Reserved - do not connect
5 P0+ Pulse output P0+ (positive line)
6 P0- Pulse output P0- (negative line)
7 P1+ Pulse or direction output P1+ (positive line)
8 P1- Pulse or direction output P1- (negative line)
9 SGND Signal ground for pulse output
10 C2..3 Input common for signals I2 and I3
11 I2 Input signal I2 (axis enable and limit switch)
12 I3 Input signal I3 (stop)
13 O1 Reserved - do not connect
14 P2+ Pulse output P2+ (positive line)
15 P2- Pulse output P2- (negative line)
16 P3+ Pulse or direction output P3+ (positive line)
17 P3- Pulse or direction output P3- (negative line)
18 SGND Signal ground for pulse output
19 UP Process voltage UP +24 VDC
20 ZP Process voltage ZP 0 VDC

Note

When wiring, the motor phase line and power line should be separated in order to avoid signal disturbances between each other.

Note

For cable length £ 30m, unshielded cable can be used with Baldor and BSD servo drives normally.

For cable length > 30m, shielded cable must be used for surge purpose.

The earthing of the shield should take place at the switch-gear cabinet, see chapter System Data AC500 System Data AC500.

The cable shields must be earthed at both ends of the cables. In order to avoid unacceptable potential differences between different parts of the installation, low resistance equipotential bonding conductors must be laid.

The internal power supply voltage for the module’s circuitry is carried out via the I/O bus (provided by a bus module or a CPU). Thus, the current consumption from 24 VDC power supply at the terminals L+/UP and M/ZP of the CPU/bus module increases by 5 mA per FM562.

The external power supply connection is carried out via the UP (+24 VDC) and ZP (0 VDC) terminals.

Warning

:strong:Removal/Insertion under power

The devices are not designed for removal or insertion under power. Because of unforeseeable consequences, it is not allowed to plug or unplug devices with the power being ON.

Make sure that all voltage sources (supply and process voltage) are switched off before you

  • connect or disconnect any signal or terminal block
  • remove, mount or replace a module.

Disconnecting any powered devices while energized in a hazardous location could result in an electric arc, which could create a flammable ignition resulting in fire or explosion.

Make sure that power is removed and that the area has been thoroughly checked to ensure that flammable materials are not present prior to proceeding.

The devices must not be opened when in operation. The same applies to the network interfaces.

Attention

:strong:Risk of damaging the PLC modules!

Overvoltages and short circuits might damage the PLC modules.

  • Make sure that all voltage sources (supply and process voltage) are switched off before you begin with operations at the system.
  • Never connect any voltages or signals to reserved terminals (marked with —). Reserved terminals may carry internal voltages.

Attention

:strong:Risk of damaging the PLC modules!

Never connect any voltages or signals to reserved terminals (marked with — or O0 / O1). Reserved terminals may carry internal voltages.

Be sure to connect the pulse output signals in the right order. Otherwise, the pulse number may be wrongly calculated and malfunctions may appear.

The module provides several diagnosis functions (see Diagnosis FM562 for Pulse Train Output).

The digital inputs can be used as source inputs or as sink inputs.

Attention

:strong:Risk of malfunctions in the plant!

A ground closure, e. g. caused by a damaged cable insulation, can bridge switches accidentally.

Use sink inputs when possible or make sure that, in case of error, there will be no risks to persons or plant.

Note

For drives/amplifiers with high-impedance pulse input interface like MicroFlex, the cable ends must be equipped with 100 Ω terminating resistors to eliminate signal reflections. Normally, the resistors are integrated in the interface connectors.
