12.8 H: Terminal Functions
842 YASKAWA SIEPC71061705H GA700 Series Technical Manual
■ 4B: During Short Circuit Braking
Setting Value Function Description
4B During Short Circuit
Braking
The terminal activates during Short Circuit Braking.
Note:
• When A1-02 = 8 [Control Method Selection = EZOLV], this function is available only when you use a PM motor.
• Refer to b2: DC Injection Braking and Short Circuit Braking on page 654 for more information.
■ 4C: During Fast Stop
Setting Value Function Description
4C During Fast Stop
The terminal activates when the fast stop is in operation.
■ 4D: oH Pre-Alarm Time Limit
Setting Value Function Description
4D oH Pre-Alarm Time Limit
The terminal activates when L8-03 = 4 [Overheat Pre-Alarm Selection = Operate at Reduced Speed (L8-19)] and oH [Heatsink
Overheat] does not clear after the drive decreases the frequency for 10 cycles.
Note:
Refer to “L8-03: Overheat Pre-Alarm Ope Selection” for more information about drive derating operation.
■ 4E: Braking Transistor Fault (rr)
Setting Value Function Description
4E Braking Transistor Fault
(rr)
The terminal activates when the internal braking transistor overheats and the drive detects an rr [Dynamic Braking Transistor
Fault] fault.
■ 4F: Braking Resistor Overheat (rH)
Setting Value Function Description
4F Braking Resistor Overheat
(rH)
The terminal activates when the braking resistor overheats and the drive detects an rH [Braking Resistor Overheat] fault.
The braking resistor overheats when the deceleration time is short and there is too much motor regeneration
energy.
■ 60: Internal Cooling Fan Failure
Setting Value Function Description
60 Internal Cooling Fan
Failure
The terminal activates when the drive detects a cooling fan failure in the drive.
■ 61: Pole Position Detection Complete
Setting Value Function Description
61 Pole Position Detection
Complete
The terminal activates when drive receives a Run command and the drive detects the motor magnetic pole position of the PM
motor.
■ 62: Modbus Reg 1 Status Satisfied
Setting Value Function Description
62 Modbus Reg 1 Status
Satisfied
The terminal activates when the bit specified by H2-08 [Modbus Register 1 Bit Select] for the MEMOBUS register address set
with H2-07 [Modbus Register 1 Address Select] activates.
■ 63: Modbus Reg 2 Status Satisfied
Setting Value Function Description
63 Modbus Reg 2 Status
Satisfied
The terminal activates when the bit specified by H2-10 [Modbus Register 2 Bit Select] for the MEMOBUS register address set
with H2-09 [Modbus Register 2 Address Select] activates.
