13.6 Rotary Switch Group
The Rotary Switch function is used to set frequency or speed of the drive.
13.6.1 Rotary Switch Group Parameters
z
Pr.118
Æ
RSW TYPE
This parameter can define the type of the Rotary Switch. There are for types can be select.
Value description
0
After RESET, the Pr.137(RSW data) will start from 0, and the max. value will be
limited by the setting of Pr.152.
1
After RESET, the Pr.137(RSW data) will start from Pr.138, and the max. value will
be limited by the setting of Pr.152.
2
After RESET, the Pr.137(RSW data) will start from 0, and the max. value will be
65535.
3
After RESET, the Pr.137(RSW data) will start from Pr.138, and the max. value will
be limited 65535.
When select 0 or 1, the speed is calculated by the equation showed below:
Rpm = Pr.137 / Pr.152 * Pr.128
When select 2 or 3, the speed is calculated by the equation showed below:
Rpm = Pr.137 / 65535 * Pr.128
z
Pr.137
Æ
RSW Data
This parameter can show the pulse count that come from the Rotary Switch A/B phase clock.
The frequency of the A/B clock is multiplied by 4 times inside the drive.
【NOTE】Because the frequency of the A/B clock, every step of the Rotary Switch will cause the
record of Pr.137 to increase 4 or decrease 4 counts.
z
Pr.138
Æ
RSW Backup Memory
This parameter defines the value that can be the default of the Pr.137 or save the Pr.137 value.
z
Pr.152
Æ
RSW Max Data Limit
This parameter defines the max. limit of the Pr.137 value.
【NOTE】Please refer to paragraph 0 11. Digital Input Function for detailed.
13.6.2 Rotary Switch Group Digital-Input
z
DIx _ Select
Æ
203，Rotary Switch signal-A input.
This function defines the terminal to be the input of Rotary Switch signal-A.
z
DIx _ Select
Æ
204，Rotary Switch signal-B input.
This function defines the terminal to be the input of Rotary Switch signal-B.
【NOTE】These two DI functions should be defined at the same time. The signal
A and B are used to define the direction and 4-times frequency accuracy
of the Rotary Switch pulse train.
z
DIx _ Select
Æ
205，Rotary Switch signal-Store input.
This function defines the terminal to be the input of Rotary Switch pulse count
store; when this function is active, the value in Pr.137 (RSW Data) will be stored
into Pr.138 (RSW Backup Memory).
