GROUP – 1: FREQUENCY SETTING
A101: Local Set Frequency (Hz)
This is the set frequency when the frequency reference input source is Local (A106=1). The output
will ramp to this frequency, when start command is given.
The minimum limit for this parameter is decided by minimum frequency A102. If A102 is set higher
then A101, the value of A102 is automatically assigned to A101.
The maximum value of this parameter is decided by Maximum frequency A103. The value of A101 6
cannot be set higher than A103.
A102: Minimum Frequency (Hz)
This is the minimum output frequency of the AC DRIVE.
In terminal mode, this is the minimum output attained with minimum analog input reference. This
value should always be lower then the maximum frequency A103. The minimum frequency will be
reached after start command with selected acceleration ramp up time. This is applicable to all
frequency references including jog select input, preset inputs and static pot inputs.
A103: Maximum Frequency (Hz)
This is the maximum output frequency of the AC DRIVE.
In terminal mode, this is the maximum output attained with maximum analog input reference.
A104: Jog Frequency (Hz)
This frequency setting is selected when executing jogging run with the programmable sequence input
command Jog Select. The selected acceleration time A201 (or A203) / deceleration time A202 (or
A204) and stop mode A304 will be applicable to this signal.
If auxiliary drive is selected, then the acceleration time D206 (or A203) / deceleration time D207 (or
A204) will be applicable.
The minimum limit for this parameter is A102 and maximum limit is A103.
Speed search function is carried out, when executing jogging run command, if it is enabled. Jog
Select is valid in all conditions of A301. However, RUN command has the higher priority then Jog
Select, if both the signals are input together.
A105: Line Speed Setting
The entered value will be displayed as motor speed in M102 at 50 Hz, if motor control mode A401=1
(open loop v/f mode). It will not have any effect in other modes.
The final speed of the driven load can be displayed by this parameter. The value to be entered can be
derived at with following formula:
