PARAMETER SETTING AND OPERATION OF PULSE/ANALOG INPUT
7-5 Torque Control
In torque control, a specified torque is applied on the servo motor by inputting an analog voltage-based torque command
into the servo amplifier.
Rotation direction is switched through "Forward selection (RS1)" input/"Reversal selection (RS2)" input.
In torque control, the torque command can be adjusted with torque command soft start used for smoothing torque
command or with the gain settings/filter settings/offset adjustment of analog torque input.
Also a speed limit can be applied on.
■ Pin assignment and wiring
For torque 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 servo amplifier has no L3/ 1/ 2 terminals.
*4
The differential line driver is equivalent to AM26C31.
*5 SG (signal groud) is short-circuited internally.
For wiring and I/O terminal specification, see "4-5 Wiring I/O Signals", Page 4-24.
