4.6 Basic Drive Setup AdjustmentsYASKAWA ELECTRIC TOEP C710606 09B YASKAWA AC Drive V1000 Installation & Start-Up Manual 139Start-Up Programming &Operation4Note: This data is for an internal dynamic braking resistor of 0.1 to 18.5 kW. For larger units, see“Dynamic Braking Resistor Unit for VARISPEED-600 Series, TOBPC72060000”◆ V/f Pattern Selection: E1-03Parameter E1-03 is only available when using V/f Control. It allows the user to set therequired V/f pattern and drive output voltage. When running a high-speed or special-purposemotor, this function fine tunes the amount of torque required for the load. Select the V/fpattern from 15 fixed V/f patterns or 1 user-programmable V/f pattern.■ Setting Instructions for Setting a V/f Pattern1. Set the input voltage for the drive. Refer to Drive Input Voltage Setting: E1-01 onpage 138.2. Select one of the two following V/f patterns:• *Select one of the 15 preset V/f patterns (setting = 0 through E)• **Select the Custom V/f pattern (setting = F)3. In case of * the following parameters are automatically set.In case of **, the following parameters are adjustable.E1-04 (Max Output Frequency), E1-05 (Max Voltage), E1-06 (Base Frequency), E1-07 (Mid Output Frequency), E1-08 (Mid Output Frequency Voltage), E1-09 (MinOutput Frequency), E1-10 (Min Output Frequency Voltage)Figure 4.24Figure 4.24 V/f Pattern■ Selecting a Preset V/f PatternThere are two types of V/f patterns: a method to select one of the 15 presets (set value: 0 toE) and a method to select arbitraty V/f pattern (set value: F). Refer to Table 4.20.No. Parameter Name Description SettingRange DefaultE1-03 V/f Pattern Selection 0 to E: Select from 15 preset V/f patterns.F: Custom V/f pattern (allows use of E1-04 through E1-10). 0 to F FOutput Voltage (V)Frequency (Hz)E1-05E1-12E1-13E1-08E1-10E1-09 E1-07 E1-06 E1-11 E1-04
