ANLG TACH VOLTS
/1000 (P.203)
Specifies the scaling
of the analog
tachometer (as it
appears on the
tachometer
nameplate) in volts
per 1000
RPM .
Parameter Range:* 18.0 to 200.0 VOLTS /1000 RPM
Default Setting: 18.0 VOLTS /1000 RPM
Parameter Type: Configurable
*Depending on the setting of GEAR IN SPEED (P.011), the high limit might be less
than 200.0 to prevent the tachometer voltage from exceeding 250V.
This parameter is only available if FEEDBACK SELECT (P.200) is set to DC TACH .
ENCODER PPR
(P.207)
Pulse encoder pulses
per revolution (
PPR )
from the pulse
encoder nameplate.
Parameter Range: 18 to 5000 PPR
Default Setting: 18 PPR
Parameter Type: Configurable
Only available if FEEDBACK SELECT is set to ENCODER .
ACCELERATION TIME (P.001)
Sets the minimum
time that the selected
speed reference can
change from zero to
GEAR IN SPEED
(P.011).
Parameter Range: 0.1 to 300.0 SECONDS
Default Setting: 5.0 SECONDS
Parameter Type: Tunable
If TRIM MODE SELECT (P.110) is set to PROPORTIONAL , the actual time to accelerate
might be modified by DRAW PERCENTAGE OUT (P.196).

ATTENTION: The incorrect configuration of ENCODER PPR (P.207) can
cause an overspeed condition. This parameter must be configured by a
qualified person who understands the significance of configuring it
accurately. Failure to observe this prcaution could result in bodily injury.
