This function provides linear acceleration and deceleration ramps in
a wider range of load conditions using tachogenerator feedback.
A DC Tacho-Generator coupled to motor must be used to provide an
analog signal feedback of 0-5VDC to terminals 7 and 8.
This function enables slow speed operation
Maximum operation time 120sec.
LO: Low Speed, 7% of rated speed.
HI: High Speed, 14% of rated speed.
Reverse direction is allowed in "High slow speed" mode only.
It provides 20% of rated speed.
This function allows dual motor control settings of acceleration,
deceleration and starting torque, and is useful to start or stop a motor
in diferent load conditions.
When this function is enabled, the parameters 2a, 2d and 2T take
over the parameters a, d and T. It allows dual motor control settings.
Allows serial communication control by SG, TD and RD terminals.

This is a programmable relay with one NO / NC dry contact to
ASTAT-CD Plus terminals 11-12-14.
This is a programmable relay with one NO dry contact to ASTAT-CD
Plus terminals 23-24.
This relay is automatically assigned to BY-Pass control if the function “z”
is ON. Any other assignment by the user is overwritten in this case.
This is a programmable relay with one NO dry contact to ASTAT-CD
Plus terminals 33-34.
This relay is automatically assigned to DC-Brake control if the
function “B” is ON. Any other assignment by the user is overwritten in
this case.

Detects unit Fault status. ON is normal status and switches OFF if a fault occurs
Detects Undervoltage according limit adjusted in function “UV”
Detects Overvoltage according limit adjusted in function “OV”
Detects unit RUN status
Detects slow speed status
Detects Undercurrent according limit adjusted in function “UC”
Detects Overcurrent limits as adjusted in function “OC”
