Field Description
15-bit velocity loop proportional gain, in fixed point with 5 fractional
bits. Range = 0 - 512.
15-bit velocity loop integral gain, in fixed point with 13 fractional bits.
Range = 0 - 2.
Motoring torque current limit (4095 = rated motor current).16-bit
speed PI controller output positive limit.
Regeneration torque current limit (4095 = rated motor current)16-bit
speed PI controller output negative limit (2’s complement)..
Motor Speed Scale factor. Spd value (in the VelocityStatus read
register group) is maintained in SPEED units of SpdScl * (Encoder
counts / Velocity Loop Execution) or SpdScl * (RATE * Encoder
counts / PWM period). The user should set SpdScl = (64 * 16384) *
60 * PWMFREQ / (RATE * Max RPM * Encoder counts/revolution),
which will result in a Spd value ranging ±16384 corresponding to ±
Max RPM.
Velocity loop speed setpoint in SPEED units, which are determined
by the user via the SpdScl register setting.
Positive speedAcceleration rate limit.
Negative speedDeceleration rate limit.
Minimum speed protection. This parameter sets the minimum
reference speed.
Drive start-up current limit. (4095 = rated motor current).
