Mitsubishi FR - S500 instruction manual Starting frequency, Name Factory

Parameter	Name	Factory	Setting	Remarks
		Setting	Range
10	DC injection brake	3Hz	0 to 120Hz
	operation frequency
				Setting is enabled when
11	DC injection brake	0.5s	0 to 10s
				Pr. 30 = "1".
	operation time
12	DC injection brake voltage	6%	0 to 15%

(When Pr. 11 is set to "0s" or Pr. 12 is set to "0%", DC injection brake is not operated.)

<Setting>

Use Pr. 10 to set the frequency at which the DC injection brake operation is started.

Use Pr. 11 to set the period during when the brake is operated.

Use Pr. 12 to set the percentage of the power supply voltage.

Change the Pr. 12. setting to 4% when using the inverter-dedicated (constant-torque motor).

If the Pr. 12 value remains unchanged from the factory setting and Pr. 71 is changed to the setting for use of the constant-torque motor, the Pr. 12 setting is automatically changed to 4%.

CAUTION

Install a mechanical brake. No holding torque is provided.

2.3.8 Starting frequency

The starting frequency at which the start signal is turned on can be set in the range 0 to 60Hz.

Parameter	Name	Factory	Setting	Remarks
		Setting	Range
13	Starting frequency	0.5Hz	0 to 60Hz	Setting is enabled when Pr. 30 = "1".

CAUTION

The inverter will not start if the frequency setting signal is less than the value set in

Pr. 13 "starting frequency".2 For example, when 5Hz is set in Pr. 13, the motor will not start running until the frequency setting signal reaches 5Hz.

CAUTION

Note that when Pr. 13 is set to any value lower than Pr. 2 "minimum frequency",

simply turning on the start signal will run the motor at the preset frequency if the command frequency is not input.
