■ 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, if the reference value in the drive
meets 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 specifications
◆ Run Command Input Selection: b1-02
This section explains how to assign the run command input.
Parameters b1-01 and b1-02 can be used to select the source of the run command
and the frequency reference independently, e.g. set the reference from the operator
and set the run command from the terminals.
