PARAMETER SETTING AND OPERATION OF PULSE/ANALOG INPUT
7-3 Position Control
In a position control, the destination coordinate can be positioned by a pulse command input from the higher-level equipment.
For SV series, a 1-pulse, 2-pulse and A/B pulse command can be input. The pulse command may be in the form of
line driver (4Mpps)/and open collector (200pps).
For position control, the "Inposition(INPOS)" signal to detect positioning completion of the servo motor as well as
"Positioning approximation(NEAR)" signal to drive the electromagnetic coil before INPOS can be used.
In addition, when a pulse command is used to drive the servo motor, the torque limit function can be used to keep the torque
within a specified range or the deviation clear function that clears position deviation as well as deviation excessive alarm/
warning function which is triggered in case the absolute position deviation is higher than the set value.
■ Pin assignment and wiring
In position control mode, the following wiring diagram can be used.
Wiring is different when using power supplies of AC 100V,
single-phase AC 200V and DC200V. Please see "Wiring the
Main Circuit/Control Circuit and Motor Power Supply
Connector", page 4-7.
*1 When an external regenerative resistor is used, the same is connected between B1/ -B2. SV-075P2/100P2/
150P2/200P2/300P2/500P2 has a built-in regenerative resistor. B2 and B3 are short-circuited. The wire
between B2 and B3 should be disconnected before the external regenerative resistor is connected.
*2 These are short-circuited when delivered. No polarity needs to be considered when connecting a DC reactor.
*3 The AC100V type has no the L3/ 1/ 2 terminals.
*4
The differential line driver is AM26C31 or similar.
*5 The wiring diagram when
the differential line driver is AM26C31 or similar. The wiring diagram for open collector
input is as follows.
*6 SG (signal ground) is short-circuited internally.
For wiring and specification of I/O terminal, see "4-5 Wiring I/O Signals", Page 4-24.
