SIEPYEUOQ2A01A AC Drive Q2A Technical Manual 69
*3 Models 4060 to 4675 have a DC reactor.
*4 When you use an optional regenerative converter, regenerative unit, or braking unit, set L8-55 = 0 [DB IGBT
Protection = Disable] to disable the protection function of the drive braking transistor. If L8-55 = 1 [DB
IGBT Protection = Enabled], the drive will detect rF [Braking Resistor Fault].
*5 When you use a regenerative converter, regenerative unit, braking unit, braking resistor, or braking resistor
unit, set L3-04 = 0 [StallP@Decel Enable = Disabled]. If L3-04 = 1 [StallP@Decel Enable = Enabled], the
drive could possibly not stop in the specified deceleration time.
*6 When you use an ERF-type braking resistor, set L8-01 = 1 [3%ERF DBR Protection = Enabled] and set a
wiring sequence to de-energize the drive with the fault relay output.
*7 When you connect a braking unit (CDBR series) or a braking resistor unit (LKEB series) to drive models
4103, make sure that you use wires that are in the range of the applicable gauges for the drive. A junction
terminal is necessary to connect wires that are less than the applicable gauge to the drive. Contact the
manufacturer or your nearest sales representative for more information about selection and installation of the
junction terminal.
*8 Cooling fan wiring is not necessary for self-cooling motors.
*9 Connect peripheral options to terminals -, +1, +2, B1, and B2.
WARNING! Electrical Shock Hazard. Use terminals -, +1, +2, B1, and B2 to connect options to the drive. Do not connect
an AC power supply lines to these terminals. Failure to obey can cause death or serious injury.
*10 Encoder circuit wiring (wiring to PG-B3 option card) is not necessary for applications that do not use motor
speed feedback.
*11 Connect 24 V power to terminal E24V-A0V to maintain power to the drive control circuit when the main
circuit is OFF.
*12 Install a wire jumper between terminals D0V-DIC-D24V to select the type of the power supply for MFDI
(sinking/sourcing mode or internal/external power supply).
NOTICE: Do not close the circuit between terminals D24V and D0V. Failure to obey will cause damage to the drive.
• Sinking Mode: Install a jumper between terminals DIC and D24V.
NOTICE: Do not close the circuit between terminals DIC and D0V in Sinking Mode. Failure to obey will cause damage
to the drive.
• Sourcing Mode: Install a jumper between terminals DIC and D0V.
NOTICE: Do not close the circuit between terminals DIC and D24V in Source Mode. Failure to obey will cause damage
to the drive.
• External power supply: Remove the wire jumper between terminals DIC-D24V and terminals DIC-D0V.
*13 The maximum output current capacity for terminals +10V and -10Von the control circuit is 20 mA.
NOTICE: Do not install a jumper between terminals +10V, -10V, and A0V. Failure to obey can cause damage to the drive.
*14 DIP switches S1-1 to S1-3 set terminals AI1 to AI3 for voltage or current input. The default setting for S1-1
and S1-3 is voltage input (“V” side). The default setting for S1-2 is current input (“I” side).
*15 DIP switch S4 sets terminal AI3 for analog or PTC input. Set DIP switch S1-3 to the “V” side, and set H3-05
= 0 [AI3 Signal Level Select = 0 to 10V (Lower Limit at 0)] to set terminal AI3 for PTC input with DIP
switch S4.
*16 Do not ground the control circuit terminals A0Vor connect them to the drive.
WARNING! Do not connect the A0V control circuit terminals to ground. Failure to obey can cause drive malfunction or
failure.
*17 Connect the positive lead from an external 24 Vdc power supply to terminal E24V and the negative lead to
terminal A0V.
NOTICE: Do not connect terminals E24V and A0V inversely. Failure to obey will cause damage to the drive.
*18 Use multi-function analog monitor outputs with analog frequency meters, ammeters, voltmeters, and
wattmeters. Do not use monitor outputs with feedback-type signal devices.
*19 Jumper switch S5 sets terminal AO1 and AO2 for voltage or current output. The default setting for S5 is
voltage output (“V” side).
*20 Set DIP switch S2 to “ON” to enable the termination resistor in the last drive in a Modbus network.
*21 Use only SOURCE Mode for Safe Disable input.
*22 Disconnect the wire jumper between H1 and HC, and H2 and HC to use the Safe Disable input.
