Function list (Simple mode parameters)

5.1.2Explanation of simple mode parameters

Refer to the separately available Instruction Manual (detailed) for details.

Pr. 1 "maximum speed", Pr. 2 "minimum speed"

!You can clamp the upper and lower limits of the output speed.

Speed setting 10V

CAUTION

Note that when you have set the minimum speed, merely turning on the start signal will start the motor at the preset speed, without the input of the speed command, according to the acceleration time setting.

Pr. 4 "multi-speed setting (high speed)" Pr. 5 "multi-speed setting (middle speed)" Pr. 6 "multi-speed setting (low speed)"

!You can select any speed (RH, RM, RL) by simply switching the external contact signal.

!You can also set each speed to any value within the range of 0 to 3600r/min during inverter operation.

!Using the extended function, you can set up to 15 speeds.

Refer to the Instruction Manual (detailed) for the setting method.

Pr. 7 "acceleration time", Pr. 8 "deceleration time"

Pr. 72 "PWM frequency"

!The time taken to reach the Pr. 20 acceleration/ deceleration reference speed (factory-set to 1500r/ min) from 0r/min is set as the acceleration time, and the time taken to reach 0r/min from the Pr. 20 (factory- set to 1500r/min) speed is set as the deceleration time.

REMARKS

!Increasing the value reduces the sound level but increases noise and leakage currents.
