Detailed Description
2.4 Drive service display (for digital drives only)
Diagnostic Tools (D1)
2-24 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Actual speed = set speed
Status display of drive.
State 0: The actual speed value is outside the speed tolerance band after a
new speed setpoint was defined.
State 1: The actual speed value has reached the speed tolerance band after a new speed
setpoint was defined.
The speed tolerance band corresponds to machine datum:
MD1426 $MD_SPEED_DES_EQ_ACT_TOL (tolerance band for 'n
set
-n
actual
' message).
The display corresponds to IS "|n
actual
|= n
setpoint
"
(DB31, ... DBX94.6).

Variable signal 1
Status display of variable signaling function of 611D.
The variable signal function monitors a memory location for violation of the defined
threshold. In addition to the threshold, a tolerance band can be defined which is also taken
into account when scanning for violation of the threshold value. The signal can be combined
with an ON delay or OFF delay time.
State 0: Threshold value not reached
State 1: Threshold value exceeded
Parameters for the variable signal function are set using the following 611D machine data:
MD1620 $MD_PROG_SIGNAL_FLAGS (Bits variable signal function)
MD1621 $MD_PROG_SIGNAL_NR (Signal number variable signal function)
MD1622 $MD_PROG_SIGNAL_ADDRESS (Address variable signal function)
MD1623 $MD_PROG_SIGNAL_THRESHOLD (Threshold variable signal function)
MD1624 $MD_PROG_SIGNAL_HYSTERESIS (Hysteresis variable signal function)
MD1625 $MD_PROG_SIGNAL_ON_DELAY (ON Delay variable signal function)
MD1626 $MD_PROG_SIGNAL_OFF_DELAY (OFF Delay variable signal function)
Diagnostics for alarms
This information is also provided as a diagnostic tool for diagnosing the causes of alarms
such as:
• "Ramp-up error"
⇒ Check the ramp-up phase to see which ramp-up phase the drive has reached.
• "Drive malfunction"
⇒ Message ZK1 is set.
⇒ Check specified parameter set, motor selection, DC link status.
Check following alarms 300500 to 300515.
