Pulse Train Input: B1-01 = 4; Configuring The Drive For Pulse Train Frequency Reference Input; Pulse Train Input Specifications - YASKAWA V1000 Series Installation & Start-Up Manual

4.6 Basic Drive Setup Adjustments
When the digital input assigned in step 2 is off, terminal A1 is the frequency reference input.
If it is closed, the A2 input value becomes the frequency reference. The active acceleration /
deceleration times are used for the change-over between the values

Pulse Train Input: b1-01 = 4

■
Setting b1-04 to 4 programs the drive so that the frequency reference is provided by the
pulse train control circuit input terminal RP.

Configuring the Drive for Pulse Train Frequency Reference Input

Setting up the Pulse Input (RP) as frequency reference input:
1. Set the reference source to pulse input (b1-01 = "4")
2. Set the pulse train input to be the frequency reference by programming parameter H6-01 =
"0" and programming the pulse train input gain to 100% (H6-03 = "100")
3. Set the pulse input scaling (H6-02) to the input frequency value which is equal to the max.
frequency reference value.
4. Apply a pulse signal to the input and check that the reference value is the desired value.
5. Readjust the pulse input gain and bias if necessary.
Note: 1. If the frequency display reaches the maximum desired frequency before the maximum pulse reference
signal is applied, increase the pulse train input scaling value (increase H6-02).
2. If the frequency display never reaches the desired maximum with the maximum pulse reference signal
applied, decrease the pulse train input scaling value (reduce H6-02)
The pulse input has the following specifications. Ensure the pulse signal meets these
