Emotron VSA Variable Speed Drive

Timing diagram is as following:
348 Jog frequency (Hz): 00.0 to 200
[342]=sleep level
Internal run command
INV sleep condition
[343]=sleep delay
wake
point
External run command
INV out frequency
PID out frequency
Sleep level (set from [342] in Hz)

351 Torque boost gain (Vector), [211]=000
Performance: If the motor load is determined to be too large
increase the output torque.
Te = I x Gain
I=load current
Gain= compensation gain

• Decrease the value in menu [351] if the motor behaviour
gets erratic.
• The max. Output torque limit to the VSD is current
rated.
• If the current gets too high when increasing the value in
menu [351] also increase the value in menu [354].
352 Low frequency voltage compensation, [211]=000
Performance: During low frequency
Increase [352] setting value to increase output voltage and
low frequency torque.
Decrease [352] setting value to decrease output voltage and
low frequency torque.

• Operating frequency range: 0 to Motor rate frequency
• Increase the value in menu [351] if the motor torque is
too low.
• Operating frequency range: 0–12 Hz/60 Hz, 0–10 Hz/
50 Hz
• During low frequency use:
When the motor output torque is insufficient, increase
[352] setting value.
