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

Attention

The FM562 must not be used as a remote expansion module at DC505-FBP, CI58x-CN, CI59x-CS31 and DC551-CS31 Bus Modules.

Note

Mounting, disassembling and electrical connection for the I/O Modules are described in detail in the S500 System Data S500 System Data, Overview.

The electrical connection is carried out by using a removable 9-pole and 11-pole Terminal Block. These terminal blocks differ in their connection system (spring terminals or screw-type terminals, cable mounting from the front or from the side). For more information, refer to the chapter Terminal Blocks for S500-eCo I/O Modules TA563-TA565 Terminal Blocks for AC500-eCo I/O Modules and AC500-eCo \ CPUs. 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 interconnect.

The assignment of the terminals:

Terminal	Signal	Meaning
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 V DC
20	ZP	Process voltage ZP 0 V DC

Note

When wiring, the motor phase line and power line should be separated in order to avoid signal disturbance 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 V DC 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 V DC) and ZP (0 V DC) terminals.

Attention

:strong:Risk of damaging the PLC modules!

The PLC modules must not be removed when the plant is powered on.

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

• connecting or disconnecting any signal or terminal block
• removing or replacing a module.

Attention

:strong:Risk of damaging the PLC modules!

The PLC modules can be damaged by overvoltages and short circuits.

• Make sure that all voltage sources (supply and process voltage) are switched off before you are beginning with operations at the system.
• Never connect any voltages or signals to reserved terminals (marked with — or O0 / O1). Reserved terminals may carry internal voltages.

Attention

:strong:Risk of malfunction in the plant!

Be sure to connect the pulse output signals in the right order.

Otherwise, the pulse number may be calculated wrong and malfunctions may appear.

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

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 through a damaged cable isolation, can bridge switches accidentally.

Use sink inputs when possible or make sure that in error case no risks will happen to persons or the plant.

The following figure shows the electrical connection of the inputs to the Pulse Train Output Module FM562:

The following figure shows the electrical connection of the Pulse Train Outputs of the FM562 to a Servo amplifier:

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.

The meaning of the LEDs is described in the Displays Pulse Train Output Module FM562.
