Preset Speed #1
Program Preset Speeds | 1 |
⇒ | ⇒ |
Up to 15 output frequency values that fall within the Lower Limit and the Upper Limit range may be programmed into the ASD and output as a Preset Speed. This parameter assigns an output frequency to binary number 0001 and is identified as Preset Speed #1. The binary number is applied to S1 – S4 of the Control Terminal Strip to output the Preset Speed.
Perform the following setup to allow the system to receive Preset Speed control input at the S1 – S4 terminals:
1. | Program | Utilities Command and Frequency Settings Frequency | ||||
| Mode #1 | Use Binary/BCD. |
|
| ||
2. | Program ⇒Terminal Settings | Input Terminals S1 (set to Set Speed 1; | ||||
| LSB of | |||||
| count) as Set Speed 2 – 4, respectively (all Normally Open). | |||||
Note: The default setting of S4 is EOff, but this terminal may be re- | ||||||
| assigned as the MSB. EOFF is a safety feature that should | |||||
| be assigned to another terminal. |
| ||||
3. | Program | Preset Speeds | 1 (set an output frequency for Preset Speed | |||
| #1; repeat for Preset Speed 2 – 15 as required). |
| ||||
4. | Program ⇒Preset Speeds ⇒Mode Enable/Disable. |
| ||||
| When Enabled, the Speed, Direction, Accel/Decel Group, V/f Group, | |||||
| and the Torque Limit Group settings for the active Preset Speed are used | |||||
| (applies to all |
|
|
|
| |
| When Disabled, only the speed setting of the active Preset Speed is used. | |||||
5. | From the Frequency Command screen (only), place the system in the | |||||
| Remote mode (LocalRemote LED Off). | ⇒ | ||||
|
|
| ⇒ |
|
| |
6. | Provide a Run command (connect F and/or R to CC). |
| ||||
Connect S1 to CC to run Preset Speed⇒ | #1 (S1 to CC =⇒0001 binary). | |||||
With S1 – S4 configured to output Preset⇒Speeds, 0001B – 1111B may be applied to S1 – S4 of the Control Terminal Strip to run the associated Preset Speed of the truth table.
If bidirectional operation is required, F and R must be connected to CC, and the Mode setting must be Enabled for a given Preset Speed being run.
With S1 being the least significant bit of a binary count, the S1 – S4 settings will produce the programmed speed settings as indicated in the truth table to the right.
