Note 1: The wiring length between the PG and inverter should not exceed 20 m. Note 2: When the PG power is 200 mA or more, use an external power supply. Note 3: The external power supply should satisfy the voltage specifications of the PG.

1.3.2 Mounting the PG to the motor

The counterclockwise rotation when viewed from the motor output shaft is regarded as "forward rotation" (see Figure 1.4). During rotation in the forward direction, the PG output pulse forms the forward signal as shown in Figure 1.5 (B phase advances 90 degrees from A phase). During rotation in the reverse direction, the PG output pulse forms reverse signal (A phase advances 90 degrees from B phase).

Mount the PG to the motor with a coupling, etc. Table 1.3 lists the correct configurations of commands, rotational directions, and motor wiring. Any other configuration fails to perform speed control

normally.

1.3.3 Wiring between the PG interface card and PG

• Turn the inverter's power OFF and wait for at least five minutes before starting connection.

• Qualified electricians should carry out wiring.

Otherwise, electric shock could occur.

• Noise may be emitted from the inverter, motor and wires. Implement appropriate measure to prevent the nearby sensors and devices from malfunctioning due to such noise.

Otherwise, an accident could occur.

1-3

Wire the PG to the PG interface card, observing the following precautions and referring to the connection diagrams given in Figures 2.1 to 2.3. (1) Turn the inverter's power OFF.

(2) Use a shielded wire for wiring between the PG and the PG interface card. (3) To prevent malfunction due to noise, keep the wiring a way from the main circuit wiring of the inverter and the power wiring of other d evices as far as

possible (at least 10 cm(3.94 in)). Do not route them in the same duct. (4) Complete the wiring for the PG before turning the inverter's power ON. (5) The wire size applicable to the option connection terminal on the inverter is AWG 18-24(0.82 to 0.2 mm

). When using a wire with its end being stripped, strip its end by 5 to 7 mm(0.2 to 0.28 in). When using a ferrule, use a vinyl-insulated ferrule. Loosen the fixing screw, insert the wire end into the opening of the terminal block, and tighten the screw.

Chapter 7 POSITIONING CONTROL

Using PG feedback signals enables positioning control. The inverter internally counts the feedback pulses and controls the motor so that the control object moves from the previously specified start point, decelerates and switches to the creep speed operation to arrive at the specified stop position. The positioning control can be enabled concurrently with the frequency control with pulse rate input and speed control with PG.

7.4 Description of the Control

The PG interface card allows the inverter to internally count feedback pulses issued from the encoder (PG) and control the motor so that the control object starts moving from the previously specified start point (S point), decelerates and switches to the creep speed operation to arrive at the specified stop position (E point).

Turning a run command ON with "Start/reset" command S/R being ON starts the positioning control. See Figure 7.1 "Positioning Control Model" and Table 7.4.

Descriptions

This specifies the start position data for the positioning control. It can be the current position [P] (absolute position) or numerical value (relative position). Specification of an absolute position and that of a relative position produce different results as described below.

[Absolute position]

Specifying [P] regards the current position as a start point. When starting the positioning control, the inverter applies the current position pulse count as start point data. (Example) Suppose that the current position pulse count = 10,000, the start point data = [P], and the stop point (E point) pulse count = 20,000. Then, when starting the positioning control, the inverter moves the control object from the current position (10,000, as start point data) to the E point (20,000). Accordingly, the object moving pulse count is 10,000 (20,000 - 10,000).

[Relative position]

Specifying "a" (numerical value) substitutes "a" for the current position data. When starting the positioning control, the inverter applies "a" pulses as start point data. (Example) Suppose that the current position pulse count = 10,000, start point data "a" = 4,000, and the stop position (E point) pulse count = 20,000. Then, when starting the positioning control, the inverter moves the control object from the start point pulse count "a" (4,000) instead of the current position data (10,000) to the E point (20,000). Accordingly, the object moving pulse count is 16,000 (20,000 - 4,000).

the inverter starts running the motor. (This covers the delay of brake OFF.) If the output frequency has not been zero (inverter running), turning the terminal command S/R ON does not start the timer count. (During deceleration triggered by turning the run command OFF, the start timer does not start as well.)

J76, J77 When the inverter detect s that the Z signal is turned from Low to High first after the LS terminal command is turned

from OFF to ON, it corrects the current position data for the preset position data (Z point). This is functionally equivalent to a mechanical position correction or origin point reset. Specifying [P] to the preset position does not perform the Z point correction. It is also possible to restrict the application of the Z point correction with the LS to the motor rotational direction

specified by function code J87. J78, J79

This specifies an absolute position pulse count required from a deceleration start point (towards the creep speed

specified by J80) to the E point.

J85 This specifies the deceleration start point that follows the end of creep-speed operation. Specify it with the pulse

count from the E point.

Take into account the inertia produced when the control object decelerates to stop. J83 This specifies the positioning allowance at the E point, that is, "Actual stop position - E point position."

After the end timer counts up:

If "Actual stop point - E point "  ER, the inverter issues the "Positioning completed" signal PSET.

If "Actual stop point - E point "  ER, the inverter issues the "Stop point alarm" signal OT.

positioning control signal. After completion of positioning, when this waiting time has elapsed or when 0.5 second has elapsed if ET < 0.5 second, the inverter issues the "Positioning completed" signal PSET or "Stop point alarm" signal OT. Turning the run command OFF when the ET is counting interrupts the counting, so the inverter does not issue PSET or OT. The inverter ensures that PSET and OT signals are kept ON for at least 100 ms.

This is used when the inverter corrects the current position data for the preset position data (Z point) specified by function codes J76 and J77.

When the inverter detects that the Z signal is turned from Low to High first after the LS terminal command is turned from OFF to

ON, it triggers the Z point correction. In any other conditions, the LS terminal command produces nothing.

This enables or disables the positioning control.

ON: Enable

OFF: Disable This enables or disables the serial pulse receiving mode. When the serial pulse input shares an input terminal with other functional pulse inputs (when the positioning control is concurrently enabled with frequency control with pulse rate input and/or speed control with PG) with function code setting, the inverter counts input pulses only from the PG for the stop position when the SPRM terminal command is ON.

SPRM

ON: Enable

OFF: Disable If the serial pulse receiving is exclusively assigned to the digital input terminal for the PG input, however, the inverter counts the input pulses for the stop position, regardless of the SPRM status. Turning the SPRM ON zero-clears the pulse count (E point data previously specified by J81 and J82). Starting the positioning control with the RTN terminal command being ON enables the return mode in which the inverter moves the control object in the reverse direction while keeping the S and E point data.

RTN

Using the RTN enables the reciprocal positioning control; moving from S to E points and returning from E to S points.

ON: Enable

OFF: Disable

The zero-clear function of the received pulse count (E point specified by J81 and J82), which can be triggered by turning the SPRMfrom OFF to ON, is always enabled. Take care not to zero-clear the E point mistakenly.

When the positioning control is enabled concurrently with the speed control with PG or frequency control with pulse rate input, the specifications of terminals [XA], [XB], [XZ], [YA], [YB], and [YZ] dif fer from the ones listed above. For details, refer to Section 7.8 "Assignment of PG Terminals When Shared." (Refer to the description of function code o01.)

7.7 Serial Pulse Receiving Function

When the S/R terminal command is assigned to any digital input terminals [X]s and the serial pulse receiving function is enabled, the pulse train input from host equipment can specify the stop position (E point). Function codes J81 and J82 (Stop position) save the input pulse count. Function code J86 specifies the pulse input mode for the serial pulse train input.

When the serial pulse receiving input shares an input terminal with other function input (e.g. Section 7.8), the inverter counts the PG input pulse train as the serial pulse receiving input for E point pulse count only when SPRMis ON. On the contrary, if the serial pulse receiving input terminal is exclusively assigned, the inverter counts the input for E point data independently the ON/OFF status of SPRM.

7.8 Assignment of PG Terminals When Shared

Table 7.12 lists input assignments for terminals [XA], [XB], [XZ], [YA], [YB] and [YZ] when the positioning control, speed control with PG and speed control with pulse rate input share the PG terminals The specifications of those terminals when shared differ from the ones when not shared.

Chapter 8 PROTECTIVE FUNCTIONS

If any inverter protective function is activated to issue an alarm, the inverter displays the corresponding alarm code on the LED monitor of the keypad and shuts down its output. Accordingly, the motor coasts to a stop. Table 8.1 lists alarm codes related to the PG interface card. For other alarm codes, refer to the FRENIC-Multi Instruction Manual (INR-SI47-1204-E), Chapter 6 "TROUBLESHOOTING."

Descriptions

• When the protective function detects an undervoltage during operation in positioning control, it issues this alarm. This alarm is contained in alarm category "Y" in Table 8.1, so it cannot be disabled by any function code.

• This protective function recognizes a PG error by software based on the position pulse feedback status against its output frequency.

• This alarm occurs if:

ero

(1) The position pulse input count does not change when the inverter output frequency has exceeded the hysteresis width

(specified by E30 Frequency Arrival, for 2.5 Hz min.) during the period longer than the timer setting specified by o18.

(2) The polarity is being incongruent between the inverter output frequency and feedback position pulse when the inverter

output frequency has exceeded the hysteresis width (specified by E30 Frequency Arrival, for 2.5 Hz min.) during th e period longer than the timer setting specified by o18.

• If the o18 data (Excessive speed deviation timer is set to 0.0 s (Disable detection), however, any alarm will not occur in both cases (1) and (2). This alarm is contained in alarm category "C" in Table 8.1.
