• 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.

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
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
Multi-Function Analog Inputs
Use the H3 Parameters to set functions to the MFAI terminals (A1, A2, A3). Refer to
Analog Input Terminal Settings on page 510
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
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.
