■ Open Loop Vector Control Method
S1-01 - Brake Release Frequency(FWD)
S1-02 - Brake Release Frequency(REV)
S1-03 - Brake Delay Frequency
S1-04 - Brake Delay Time
S1-05 - Brake Release Current (FWD)
S1-06 - Brake Release Current (REV)
S1-07 - Brake Release Torque (FWD)
S1-08 - Brake Release Torque (REV)
S1-09 - Torque Compensation (FWD)
S1-10 - Torque Compensation (REV)
S1-11 - Torque Compensation Delay Time
S1-12 - Brake Hold Frequency (FWD)
S1-13 - Brake Hold Frequency (REV)
S1-14 - Slip Prevention Frequency
S1-15 - Slip Prevention Time
b2-01 - DC Injection/Zero SpeedThreshold
E1-09 - Minimum Output Frequency
Note:
Note the following precautions regarding the use of torque forcing.
• Torque forcing is used to perform the following operations. The operation is selected with S1-09.
–Compensate for slipping that occurs with heavy loads.
–Release brakes as quickly as possible (shorten operation cycles).
• When S1-04 = 0, torque forcing per S1-09 or S1-10 is active until the output frequency reaches the setting value of either S1-01 or S1-
02.
