C0010
Properties "minimum output frequency":
ƒ C0010 is approached via the acceleration ramp.
ƒ C0010 has no effect
– on analog input 2 of the application I/O.
– if the setpoint is selected via frequency input.
ƒ C0010
³C0011 (from software version 3.5):
– the output frequency is 0 Hz. The drive is at standstill.
ƒ C0010
³C0011 (software version < 3.5):
– independent of the selected analog setpoint, C0011 is approached via the
acceleration ramp.
– the output frequency is limited to C0011.
– the gain of the analog input must be set to zero (C0027 = 0) to ensure trouble−free
operation.
C0011
Properties "maximum output frequency":
ƒ When selecting fixed setpoints (JOG), C0011 acts as limitation.
ƒ C0011 is an internal scaling variable! Therefore major changes may only be carried
out when the controller is inhibited!
(
Stop!
Set 0011 so that the maximum permissible motor speed is not exceeded.
Otherwise the motor may be destroyed.
C0239
Properties "lower frequency limitation":
ƒ During operation with standard I/O, C0239 is approached without acceleration ramp
(jerk!). During operation with application I/O, an acceleration time can be set for
C0239 in C0236.
ƒ C0239 = 0.00 Hz only allows for one direction of rotation.
Setting tips
ƒ In case of output frequencies > 300 Hz, avoid switching frequencies < 8 kHz.
ƒ The display values in C0010 and C0011 can be related to process variables by means
of C0500 and C0501.
