■ Operation When the External Baseblock Command is Input
• The drive executes baseblock (drive output stop) for at least 0.1 s.
When using the brake sequence, the Brake release command is switches OFF.
• Set SFS Output Frequency to 0.
■ Operation When the External Baseblock Command is Cleared
• Acceleration always starts from the zero speed when the Run command is input.
• The baseblock state is maintained when the Run command is not input.
◆ Speed Reference
■ Speed Reference Method Selection
You can select how to enter the speed reference to the drive with b1-01 [Frequency Reference Selection 1].
b1-01 Setting Name Description
0 Keypad Use the keypad to enter the speed reference.
1 Analog Input Use the MFAI terminals A1, A2, and A3 to enter the speed reference.
2 MEMOBUS/Modbus Communications Use MEMOBUS/Modbus communications to enter the speed reference.
3 Option PCB Use an input option card to enter the speed reference.
■ Input Signal Setup
Multi-Funciton Digital Inputs (Terminals S1 to S10)
Use the H1 Parameters to set functions to the MFDI terminals (S1 to S10). For more information about MFDI
functions, refer to
H1-xx: MFDI Setting Values on page 500.
Multi-Function Digital Outputs
Use the H2 Parameters to set functions to the MFDO terminals (M1-M6, MA, MB, MC, P1-C1, P2-C2). Refer to
H2-xx: MFDO Setting Values on page 505 for more information about MFDO functions.
Multi-Function Analog Inputs
Use the H3 Parameters to set functions to the MFAI terminals (A1, A2, A3). Refer to
H3-xx: Multi-Function
Analog Input Terminal Settings on page 510
for more information about MFAI functions.
Multi-Function Analog Outputs
Use the H4 Parameters to set functions to the MFAO terminals (FM, AM). When you enter the “x-xx” part of the
monitor Ux-xx, you can set the MFAO functions. Refer to
U: Monitors on page 539 for more information about
the monitors.
◆ Brake Sequence
To ensure the appropriate amount of torque for the load at start and stop when opening and closing the brake, the
Brake release command is output based on the drive internal frequency reference, the motor current, and the
torque reference.
