F07080 — Drive: Incorrect control parameter

F07080 is raised when the drive checks its closed-loop control parameters and finds one of them set incorrectly. The manual's example is p0356 (motor stator leakage inductance, L_spread) set to 0. The fault value in r0949 contains the number of the parameter involved, so the code identifies exactly which setting to correct; the message value displays it as Parameter: %1.

• The closed-loop control parameters have been parameterized incorrectly — one of them holds a value the drive cannot use. The example the manual gives is p0356 = L_spread = 0.

1. Read the fault value in r0949 and interpret it as a decimal number; it contains the number of the parameter that raised the fault.
2. Open that parameter and check its setting. The manuals cross-refer the following parameters for this fault: p0310, p0311, p0341, p0344, p0350, p0354, p0356, p0357, p0358, p0360, p0400, p0404, p0408, p0640, p1082 and p1300.
3. Correct the value the fault points to — the manual's example is p0640 (current limit), which must be set to a value greater than 0.
4. Acknowledge the fault with a POWER ON.

• The fault value is read in r0949 and is to be interpreted as a decimal number; it contains the parameter number involved.
• The message value is Parameter: %1, where %1 is that parameter number.

• r0949 (Fault value) — read here, interpreted as a decimal, to see which parameter number triggered F07080.
• p0356 (Motor stator leakage inductance / Mot L_stator leak) — the manual's example of an incorrect setting is 0 here (p0356 = L_spread = 0).
• p0640 (Current limit) — the manual's example correction: set the current limit to a value greater than 0.
• p0310 (Cylinder piston diameter / Cyl piston diam) — check the setting if r0949 names this parameter.
• p0311 (Cylinder piston rod diameter A side / Cyl PistRodDiam A) — check the setting if r0949 names this parameter.
• p0341 (Cylinder weight / Cyl weight) — check the setting if r0949 names this parameter.
• p0344 (Cylinder mounting position A side / Cyl mount pos A) — check the setting if r0949 names this parameter.
• p0350 (Damping uncontrolled axis / Damp unctrl axis) — check the setting if r0949 names this parameter.
• p0354 (Axis natural frequency B side / Axis fn B) — check the setting if r0949 names this parameter.
• p0357 (Motor stator inductance d axis / Mot L_stator d) — check the setting if r0949 names this parameter.
• p0358 (Motor rotor leakage inductance / damping inductance d axis / Mot L_r leak / LDd) — check the setting if r0949 names this parameter.
• p0360 (Motor magnetizing inductance/magn. inductance d axis saturated / Mot Lh/Lh d sat) — check the setting if r0949 names this parameter.
• p0400 (Encoder type selection / Enc_type sel) — check the setting if r0949 names this parameter.
• p0404 (Encoder configuration effective / Enc_config eff) — check the setting if r0949 names this parameter.
• p0408 (Rotary encoder pulse number / Rot enc pulse no) — check the setting if r0949 names this parameter.
• p1082 (Maximum velocity / v_max) — check the setting if r0949 names this parameter.
• p1300 (Open-loop/closed-loop control operating mode / Op/cl-lp ctrl_mode) — check the setting if r0949 names this parameter.

Correct the parameter named in r0949 first, then acknowledge the fault. The manuals specify acknowledgement IMMEDIATELY with POWER ON, i.e. the fault is cleared by switching the drive off and on again once the parameter has been corrected.
