6. Control Functions and Parameter Settings6-27Block-C parameters (Extended function constants) listApplicationNo. Parameter Unit Default Min. Max. FunctionST V/f VEC PMC20 – Start interlock0 Start/stop frequency(speed)% 0.0 0.0 20.0 The motor will stop when below thisfrequency setting.1 Start/stop frequency(speed) hysteresis% 1.0 0.0 20.0 2 Interlock frequency(speed)% 0.0 0.0 20.0 The motor will not start when thespeed or frequency setting is lowerthan this frequency.When C20-0=0, the setting start/stopwill not operate.When C20-2=0, the setting interlockwill not operate.3 RUN delay timer sec 0.00 0.00 10.00 Delays F RUN or R RUN operation C21 – Retry/pick-up0 Number of retries 0. 0. 10.

Do not set a value less than theexcitation current.C22 – Overload0 Overload setting % 100. 50. 105. Note that when this parameter ischanged, Parameters C22-1 andC22-2 will automatically be adjustedto the value of this setting.1 0Hz overload % 100. 20. 105. The maximum value is as set onC22-2.2 0.7Base freq.overload % 100. 50. 105. The minimum value is as set onC22-1.4 Motor loss brakingsetting% 50.0 0.0 70.0 This function is valid when controlmode selection is C30=1,2 and DBRoption selection is C31-0=3,4C22-0~2: The max. value differs according to the load characteristic selection (C30-0).When C30-0=2 (when variable torque is selected), these max. value is 100.C23 – Start/Stop frequency-Overload (Dual drive)0 Start frequency Hz 1.0 0.1 60.0 1 Stop frequency(DC Brake start)Hz 1.0 0.1 60.0 2 Overload setting % 100. 50. 105. Note that when this parameter ischanged, Parameters C23-3 andC22-4 will automatically be adjustedto the value of this setting.3 0Hz overload % 100. 20. 105. The maximum value is as set onC22-4.4 0.7Base freq.overload % 100. 50. 105. The minimum value is as set onC22-3.
