b2-04 DC Inject Braking Time at Stop -
E1-09 Minimum Output Frequency -
*1 This parameter is enabled when A1-02 = 2, 3, or 4 [Control Method Selection = Open Loop Vector, Closed Loop Vector, Advanced
Open Loop Vector].
*2 The names of parameters S1-09 to S1-11 change according to the control method that is selected.
Example
• When A1-02 = 2, the name of S1-09 is [Torque Forcing (FWD)].
• When A1-02 = 3, the name of S1-09 is [Torque Compensation (FWD)].
*3 Enabled when A1-02 = 2 [Control Method Selection = Open Loop Vector].

Setting Value
Name Description
21 Brake Release Command
When terminal is ON, it functions as the brake release command.
■ Description of Operation
The following time chart shows the terminal functions when b1-01 = 1 [Frequency Reference Selection 1 =
Analog Input], b1-02 = 1 [Run Command Selection 1 = Digital Input].
• Terminals S1, S2 (Forward run command, Reverse run command)
Terminals receive the Forward run command and Reverse run command. The signal combinations work as
shown below.
However, the following operations may be restricted based on the Run command tuning function. Refer to
Adjusting the Run Command on page 204 for details.
Forward Run
Command
Reverse Run
Command
Operation Ref.
OFF OFF
Ramps to stop according to the stop sequence.
200
ON OFF
The motor rotates in the forward direction.
-
OFF ON
The motor rotates in the reverse direction.
-
ON ON
The keypad shows SE1 [Brake Sequence Fault 1 (SE1)], and the motor will coast to stop.
The Brake release command is switched OFF as soon as the fault occurs, and the brake closes.
Note:
When S1-16 [Sequence Fault SE1 Detect Time] = 0.00, then the keypad shows EF [FWD/REV
Run Command Input Error], and the motor will ramp to stop. A fault signal is not output at this
time.
-
Note:
• Note the following when the Run command source is set to the keypad.
–When b1-02 = 0 [Run Command Selection 1 = Keypad], the brake sequence set with S1-xx parameters will not function.
–Make sure that the Run command is not issued from the keypad when connecting the brake signal to the drive. If the Run command is
issued from the keypad, then the brake may slip or drive overload may result because the brake will not be released.
–If Auto-Tuning is executed after the Brake release command signal is connected to the drive, then the drive will show Er-09
[Acceleration Error] or Er-11 [Motor Speed Error], and abandon the Auto-Tuning procedure.
• Make sure to include an external sequence for the drive in order to release the brake after the Brake release command is switched ON,
and also to close the brake after the Brake release command is switched OFF. Refer to the standard connection diagram in
Electrical
Installation on page 71
for information about the connection of the control circuit I/O terminals.
