Turn on the STF signal to start forward
rotation and turn it off to stop.
Turn on the STR signal to start reverse
rotation and turn it off to stop.
The function of the terminals changes
according to the input terminal function
selection (Pr. 187) setting.
Refer to page 65 for details.
The terminal functions vary with the input terminal function selection (Pr. 180 to Pr.
183) settings. Refer to page 65 for details.
Temperature sensor terminal input for motor overheat protection.
OHT error occurs when terminals OH and SD are open.
Used to reset alarm output provided when protective circuit is activated. By setting
Pr. 75 "reset selection", reset input possible or reset input possible only during
protective circuit operation can be selected. Turn on the RES signal for more than
0.1s, then turn it off.
Common to the contact input. Common output terminal for 24VDC 0.1A power
supply (PC terminal).
Isolated from terminals 5 and SE.
When connecting a transistor output (open collector output), such as a
programmable controller, connect the external power supply common for transistor
output to this terminal to prevent a malfunction caused by a sneak current.
PC-SD can be used as a 24VDC, 0.1A power supply. Note that this connection does
not prevent undesirable currents.
When source logic has been selected, this terminal serves as a contact input common.
10VDC, permissible load current 10mA
By entering 0 to 10VDC, the maximum output speed is reached at 10V and I/O are
proportional. Acts as a speed command terminal for speed control or as a speed
limit for torque control. Input resistance 10k Ω , maximum permissible voltage 20V.
Acts as a torque setting signal for torque control or a torque limit signal for speed
control and position control.
Acts as an input terminal when torque bias function by external analog is selected.
0 to ±10VDC input, input resistance 10k Ω , maximum permissible voltage ±20VDC
Since this is a multi-function selection terminal, its function varies with the Pr. 868
"terminal 1 function assignment" setting. The function of this terminal is factory-set to
adding auxiliary of speed setting terminal of terminal 2.
Refer to Pr. 868 "terminal 1 function assignment" in the Instruction Manual (detailed).
0 to ±10VDC input, input resistance 10k Ω , maximum permissible voltage ±20V
Speed setting signal (terminal 2, 1 or 3) common terminal.
Isolated from terminals SD and SE. Do not earth (ground).
A-, B- and Z-phase signals are input from the encoder.
The jumper connector is factory-set to complimentary. Thus, the encoder need not
be connected to PAR, PBR, and PZR.
Power supply for encoder. You can switch the power supply between 5 (5.5), 12 and
24VDC.
You can also switch to external power supply.
The jumper connector is factory-set to 12VDC. (Refer to page 12.)
Common terminal for the encoder power supply.
Isolated from terminals 5 and SE.
Do not earth (ground).

Description
When the STF and STR signals are
turned on simultaneously, the stop
command is given.
