TOEP C710617 17B YASKAWA AC Drive GA700 Initial Steps
*2
Terminals -, +1, +2, B1 and B2 are the optional connection terminals.
NOTICE
Do not connect an AC power supply to terminals -, +1, +2, B1, and B2. Failure to obey can cause
damage to the drive and peripheral devices.
*3
Be sure to remove the short bar between the ter1 and +2 when installing the optional DC reactor.
*4
Models 2110 to 2415 and 4060 to 4675 have a built-in DC reactor.
*5
Be sure to set
L8-55 = 0 [InternalBrakingTransistorProtect = Disable]
when using the regenerative
converter, regenerative unit or the braking unit (when not using the built-in dynamic braking transistor).
rF
[Braking Resistor Fault]
may be triggered.
*6
Set
L3-04 = 0 [Decel Stall Prevention Selection = Disabled]
to disable Stall Prevention when using a
regenerative converter, regenerative unit, dynamic braking unit, braking resistor, or braking resistor unit. If
left unchanged, it may not stop at the set deceleration time.
*7
When using a braking resistor (ERF type), set
L8-01 = 1 [Internal DB Resistor Protect Sel (ERF type) =
Provided]
and be sure to use a sequence that shuts the power off by using the fault relay output for the drive.
*8
Wiring for the cooling fan motor is not required with the self-cooling motor.
*9
Supplying power to the control circuit separately from the main circuit requires a 24 V power supply be
input to terminal PS-AC.
*10 Encoder circuit wiring (wiring on the PG-B3 option card) is not required when using the drive in an
application that does not use feedback from the motor.
*11 Install a jumper between terminals SC-SP-SN to select the type of the power supply of MFDI.
NOTICE
Do not short circuit terminals SP and SN. Failure to obey will cause damage to the drive.
•
Sinking mode: Short terminals SC and SP.
•
Sourcing mode: Short terminals SC and SN.
•
External power supply: No jumper necessary.
*12 The maximum output current capacity of the +V and -V terminals on the control circuit terminal is 20 mA.
NOTICE
Do not install a jumper between terV, -V, and AC. Failure to obey can cause damage to the
drive.
*13 Set DIP switches S1-1 to S1-3 to select between a voltage or current input command to terminals A1 to A3.
The default setting for S1-1 and S1-3 is voltage reference input (
“
V
”
side). The default setting for S1-2 is
current reference input (
“
I
”
side).
*14 Set DIP switch S4 to select between an analog input or PTC input to terminal to A3. After the PTC input has
been selected, set DIP switches S1-3 to the V side, and set
H3-05= 0 [0-10V (LowLim=0)]
.
*15 Do not connect terminals PS and AC inversely. Failure to comply will damage the drive.
*16 Monitor outputs work with devices such as analog frequency meters, ammeters, voltmeters, and wattmeters.
They are not intended for use as a feedback-type of signal.
*17 Set jumper switch S5 to select between a voltage or current output to terminals FM and AM. The default
setting is V-side (voltage output).
*18 Enable the termination resistor in the last drive in a MEMOBUS/Modbus communications by setting DIP
switch S2 to the ON position.
*19 Use sourcing mode for Safe Disable input.
*20 Disconnect the wire jumper between H1 - HC and H2 - HC when utilizing the Safe Disable input.

Wire Gauge and Torque Specifications
Be sure to select the correct wires for the main circuit wiring.
Refer to the Technical Manual for main circuit wire gauges and tightening torques as specified by European
standards and UL standards.
■
Main Circuit Wire Gauges and Tightening Torques
Use the tables in this section to select the appropriate wires. Use shielded wire when wiring the control circuit
terminal block. For simpler and more reliable wiring, use crimp ferrules on the wire ends.
The tightening torque for the control circuit terminal is displayed on the reverse side of the front cover.
