DRV-00: Command Frequency / Output Current
1) Digital frequency setting
This parameter is used to set the command frequency
when DRV-04 [Frequency Mode] is set to Keypad-1 or
Keypad-2. It can be set to a value equal to or less than
FUN-30 [Maximum Frequency].
2) Monitoring function setting
The command frequency is displayed during stop.
Output current and frequency are displayed during run.
When DRV-04 [Frequency Mode] is set to V1, V1S, I,
V1+ I or Pulse the drive will display the reference
frequency during stop.
If PID control is active the user can change the units to
be displayed in I/O-86.
When DRV-17 [Speed Unit Selection] is set to Rpm,
the display will show RPM rather than Hz.
DRV-01, 02: Accel/Decel Time
The acceleration time is the amount of time that it takes
(from zero Hz.) for the drive to reach the maximum
frequency set in FUN-30 when the drive receives a
start command. The deceleration time is amount of
time the drive takes to stop from the maximum
frequency in FUN-30 to 0Hz when a stop command is
given.
When FUN-73 is set to “Delta Frequency”, the
acceleration and deceleration time is the time taken to
reach a target frequency (instead of the maximum
frequency) from a specific frequency.
Note: Set the Accel time more than 0.5 sec for
smooth acceleration. Setting it too short may
deteriorate the starting performance.
DRV-03: Drive Mode (Run/Stop Method)
This parameter selects the source of run/stop command.
