1 : Control Circuit Terminal
Allows the run command via the digital input terminals using the following sequences.
□ 2-Wire Sequence
Two inputs (forward/stop, reverse/stop). Set E1-00 (Terminal S1 Function Selection) to 0
(Forward/Stop) and E1-01(Terminal S2 Function Selection) to 1(Reverse/Stop). Refer to Page
112 for instructions.
□ 3-Wire Sequence
Three inputs (forward, stop, forward/reverse). Set A1-03 = 3330 to reset the drive and
automatically assign the 3-wire sequence control function to terminals S1, S2 and S5. Refer
to Page 113 for instructions.
2 : Modbus Communication
Allows Run commands via the Modbus communication. Make sure RS-485/422 serial
communications port is connected to control circuit terminals J1 and J4.
b1-02 Stopping Method Selection
Selects the way the drive stops the motor when a Stop command is entered or the run
command is removed.
Stopping Method Selection
0 : Ramp to Stop
The drive will decelerate the motor according to the active deceleration time. The default of
deceleration time is set in C1-01. The actual deceleration time will be changed depending on
the load characteristics such as inertia.
When decelerating a load with high inertia, the drive perform ramp-to-stop first and then start
DC braking to fully stop the motor. Refer to “b2 Group, DC Braking”for details.
□ For Open-Loop V/F Control, Closed-Loop V/F Control, Open-Loop Vector Control and
PM Open-Loop Vector Control:
When the output frequency falls below b2-00, DC Braking is enabled for the time set in
b2-03. Refer to Figure 6.3.
