5.5 E: Motor Parameters
E parameters cover V/f pattern and motor data settings.
◆ E1: V/f Pattern for Motor 1
■ E1-01: Input Voltage Setting
Set the input voltage parameter to the nominal voltage of the AC power supply. This parameter adjusts the levels of some
protective features of the drive (overvoltage, Stall Prevention, etc.).
NOTICE: Set parameter E1-01 to match the input voltage of the drive. Drive input voltage (not motor voltage) must be set in E1-01 for
the protective features of the drive to function properly. Failure to comply could result in improper drive operation.
E1-01 Related Values
The input voltage setting determines the over-/undervoltage detection level and the operation levels of the braking
transistor as well as the KEB function and the overvoltage suppression function.
Note: The braking transistor operation levels are valid for the drive internal braking transistor. If an external CDBR braking chopper is
used, refer to the instruction manual TOBPC72060000.
■ V/f Pattern Settings
The drive utilizes a set V/f pattern to determine the appropriate output voltage level for each relative to the frequency
reference.
One custom V/f pattern can be set up by programming parameters E1-04 through E1-13.
V/f Pattern Setup
1.
Set the input voltage for the drive. Refer to E1-01: Input Voltage Setting on page 147.
2. To set up a V/f pattern, E1-04 through E1-13 must be adjusted manually. Refer to V/f Pattern Settings E1-04 to
E1-13 on page 148.
■ E1-03: V/f Pattern Selection
This parameter can only be set to “F”.
No.
