4.4 Basic Parameter AdjustmentsYASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07) 133Start-Up Programming &Operation4■ Pulse Train Input (b1-01 = 4)Setting b1-04 to 4 programs the drive so that the frequency reference is provided bythe pulse train control circuit input terminal RP.Configuring the Drive for Pulse Train Frequency Reference InputSetting 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 programmingparameter 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 tothe max. frequency reference value.4. Apply a pulse signal to the input and check, if the reference value in the drivemeets 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 maximumpulse reference signal is applied, increase the pulse train input scaling value (increaseH6-02).2. If the frequency display never reaches the desired maximum with the maximum pulsereference signal applied, decrease the pulse train input scaling value (reduce H6-02)The pulse input has the following specifications. Ensure the pulse signal meetsthese specifications◆ Run Command Input Selection: b1-02This 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 commandand the frequency reference independently, e.g. set the reference from the operatorand set the run command from the terminals.Pulse Train Input SpecificationsResponse Frequency 0.5 to 32 kHzDuty Cycle 30 to 70%High Level Voltage 3.5 to 13.2 VLow Level Voltage 0.0 to 0.8 VInput Impedance 3 kΩ
