Func
tions
External Thermistor (TH)
• This function enables thermal protection of the external equipment (e.g. motor) if its internal
thermistor is connected to the Inverter.
Note: If thermistor selection b098 is set to "01" without connecting an external thermistor, the Inverter trips.
• Connect an external thermistor between control terminals TH and SC.
• Set the following functions according to the specifications of your thermistor.
• When this function is used, keep the cable length between the motor and Inverter within 20 m.
Since the current flowing through the thermistor is weak, you must take measures to prevent noise
due to motor current. (For example, place the thermistor cable away from the motor cable.)
Brake Control Function
• This function allows the Inverter to control the external brake of equipment, including an elevating
system. When brake control selection b120 is set to "01" (enabled), the Inverter operates as
follows:
(1) At RUN command input, the Inverter starts output, and accelerates to the release frequency.
(2) After the release frequency is reached, the Inverter outputs the brake release signal (BRK) after
the brake release establishment wait time (b121) elapses. However, if the Inverter's output
current is less than the current value set in release current b126, the Inverter does not output
the brake release signal. In this case, the Inverter trips, and outputs the brake error signal (BER).
(3) If the brake confirmation signal (BOK) is allocated to a multi-function input (when "44" is set in
any of C001 to C008), the Inverter waits for the brake confirmation signal for the period set in
brake confirmation wait time b124 without accelerating, after the brake release signal is output.
If the brake confirmation signal does not turn on within the period set in b124, the Inverter
outputs the brake error signal (BER), resulting in trip. If the brake confirmation signal is not
allocated to a multi-function input, brake confirmation wait time b124 is disabled, and the Inverter
performs processing (4) after the brake release signal is output.
(4) After the brake confirmation signal is input (or after the brake release signal is output if BOK is
not selected), the Inverter restarts acceleration up to a set frequency after the period set in
acceleration wait time b122 elapses.
(5) After the RUN command is turned off, the Inverter decelerates to the brake release frequency
(b125), and turns off the brake release signal (BRK).
