7-3 Description of Functions
Note 1: This function (F1112) enables during V/f control mode (F1001=1 or 40). When the inverter run speed control
mode (F1001=2 or 3), this function can set by F6005 and F6006.
Note 2: During DC braking, the motor has possibility over heat, because the motor is very low speed and self cooling
effect is down. Therefore DC braking force set small value, keeping motor cool level. We recommend using a
thermal relay.
Note 3: If DC braking force set big and braking force don’t change, then the motor becomes over current by something
reason and the inverter is protected by current limiter.
F1115 Duty cycle of brake resistor
A function for setting utilization rate of a brake resistor. The value shall be set within the allowable utilization rate of the
brake resistor.

Presets
F1115 Duty cycle of brake
resistor
0: No brake resistor
2-25%ED
98: No discharge resistor protection (with
discharge *1)
99: External brake unit
1%ED *2
Note: In case of braking through an external circuit, please set F1115 = 99.
*1 Since the protection actions will not be executed when F1115 = 98, the discharge resistor and the device may be
damaged. Please note this when setting.
*2 The representative parameters that are suitable for various models have been input.
When setting F1115 = 2-25, if it is judged that excessive current will flow in the brake resistor for a long time, in order to
prevent the brake resistor connected from burning damage, the actions of braking circuit drive element shall be stopped in
a certain period of time.
F1116 Discharge resistor on signal output time
This function is used to output signals from a multifunctional output terminal for the time set with F1116 when the
discharge resistor for regenerated power discharge is turned on.

F1116 Discharge resistor on signal
output time
0.01 -10 sec. 0.01 s 0.1
●
Set one of F1509-F1511 to―32‖ for the multifunctional output terminal setting. The discharge resistor on signal is
output from the terminal which is set to―32‖.
●
During regenerated energy discharge, the discharge resistor switches between ON and OFF very quickly and
repeatedly. The Discharge Resistor on Signal function facilitates the measurement of this high-speed on/off
operation with a narrow pulse width in external equipment. The narrow pulse width of the on/off operation is
expanded by the time set with F1116 and output by a multifunctional output terminal.
Example) When the Discharge Resistor on Time F1116=0.1 [s].
